In the world of Scala programming, case classes hold a unique and powerful position, offering functionalities that make them invaluable for developers. Whether you're new to Scala or looking to deepen your understanding, this guide will explore what case classes are and why they are essential in the Scala ecosystem. A case class in Scala is a special type of class that provides additional functionality compared to a regular class. It is defined with the case keyword, followed by the class keyword. Case classes are primarily used for modeling immutable data and come with several pre-defined methods that make them convenient to use. Immutable by Default: Case classes automatically come with val parameters, which makes their properties immutable unless explicitly defined with var. Automatic…  ( 4 min )

This is a submission for the Postmark Challenge: Inbox Innovators. I built InboxHire, a personal AI-powered job application assistant that helps job seekers track and manage their job applications automatically—just by forwarding their application emails. No more copy-pasting details into spreadsheets or forgetting which company emailed you what. InboxHire listens to your email (via Postmark), extracts structured data using Gemini AI, and organizes everything in a sleek dashboard. Lets face it — being a job seeker these days is basically a full-time job... without the paycheck. You are probably juggling applications across every corner of the internet: 🔗 LinkedIn – Where "Open to Work" becomes a lifestyle. 🔥 Naukri.com – Where you uploaded your resume once... and they still email you da…  ( 5 min )

From day one, the goal of Shrimp has never been just to delegate or break down tasks to an AI assistant, but to develop an assistant that possesses true upstream and downstream thinking—just like an engineer. However, during development, I quickly realized something: before most engineering tasks even begin, what’s truly needed isn’t “execution” — it’s “research.” That’s why in this update, I introduced the brand-new Research Mode. This article will walk you through its design rationale, practical workflow, and a full experiment I conducted using it. In software development, the most common issue isn’t “not knowing what to do,” but rather not knowing which solution is more appropriate. Here’s a real example: say I want to optimize Laravel’s search capabilities. The potential options includ…  ( 5 min )

tl;dr – tsc.run (short for TypeScript Cloud) is now in public alpha. Write a function, export it, and let the framework handle everything from routing to deployment. Type‑Safe Serverless – end‑to‑end type safety: requests, responses, events. Convention Over Configuration – opinionated project layout, minimal boilerplate. Simplified Deployment – one streamlined CLI; no Docker, no ZIP juggling. Multi‑Cloud Roadmap – AWS first, more providers to follow. Automatic Function Discovery – REST routes, jobs, and subscribers: just export & deploy.

If you’re building any kind of real application, sooner or later you’ll be wrangling dates and times. And the moment your users live in different time zones, things get… interesting. I’ve hit this wall dozens of times — each encounter requiring a quick mental reset, a bit of digging, and a careful rethink of how to handle it all correctly. There’s a fantastic (and slightly terrifying) post on the topic — Falsehoods Programmers Believe About Time — that’s absolutely worth a read. But today, I want to zero in on one specific gotcha: how JavaScript parses ISO date strings, and why new Date(str) and parseISO(str) from date-fns might not behave the way you expect. In the project I was reviewing, dates were stored in ISO 8601 format—but in three different ways: Full datetime with a trailing Z (e…  ( 5 min )

Imagine pedir uma informação para uma ferramenta de inteligência artificial e ela responder com confiança… só que está completamente errada. Não por má intenção, mas porque "alucinou". Sim, alucinações não são exclusividade do cérebro humano, o termo também é usado para descrever respostas inventadas por sistemas de IA generativa como ChatGPT, Gemini ou Bard. Mas o que isso significa? O que são “alucinações” em IA? As “alucinações” mais comuns são o uso de citações que nunca existiram; de dados estatísticos sem fonte confiável; de títulos de livros atribuídos a autores errados; de fatos plausíveis, mas sem qualquer base real. “Esses erros acontecem porque a IA não entende o que está dizendo, ela apenas prevê qual palavra tem mais chance de vir a seguir com base em dados anteriores”, explica a editora-chefe da Atena Editora, Antonella Carvalho de Oliveira. Por que a IA “alucina”? Por isso eles não sabem identificar alguns erros ou verificar informações mais subjetivas ou complexas, principalmente em áreas mais sensíveis como pesquisa acadêmica, medicina, direito ou jornalismo, e isso é um risco grave. Dicas para corrigir (ou evitar) alucinações da IA?: Sempre revise manualmente o conteúdo gerado, a IA é um assistente, não um autor final; Use fontes confiáveis para checagem, como dados oficiais, artigos científicos ou veículos jornalísticos de referência; Evite usar IA para citar autores, livros e dados exatos sem conferência; Use ferramentas com acesso a dados atualizados, quando disponíveis, ou peça que ela cite as fonte e verifique-as; Se possível, combine IA com supervisão especializada, principalmente em áreas técnicas. A responsabilidade ainda é humana “Combinando inteligência artificial com revisão humana, conseguimos um conteúdo mais ágil e, ao mesmo tempo, responsável”, alerta Antonella Carvalho de Oliveira.  ( 4 min )

Hey devs, But every time, I'd end up writing the same boilerplate: set up Express, add auth, handle errors, deploy somewhere, configure rate limiting... you know the drill. I was using Beeceptor for mocking APIs during development (great tool btw), but I kept thinking "what if this could actually run real logic?" Like, what if I could just drag some components together and have a production API ready in minutes? I am a novice builder, so my code is basically a combination of a few reusable code blocks I copy-paste from one file to another. That's how I ended up building CFFBRW (www.cffbrw.com). Started as a weekend project to scratch my own itch.

If you’re building or scaling ML projects in 2025, chances are you’ve already bumped into the same question we had: Both platforms offer powerful tools, automation features, and enterprise-level support. But they also come with key differences, in pricing models, ease of use, ecosystem fit, and even how they handle MLOps workflows. We made a side-by-side comparison in video form to make the choice easier. Here’s what we cover: 🧠 Ease of use – How beginner-friendly is each platform, and what’s the learning curve like? 🔌 Integrations – How well do they plug into their respective cloud ecosystems (and open-source tools)? 🚀 Performance & scaling – How do they handle large models, training pipelines, and distributed workloads? 💵 Pricing flexibility – Which one gives you more control over costs? 🔐 Security & compliance – Important if you're working in regulated industries like healthcare or finance. Whether you're a solo dev experimenting with models, or working on production-level ML pipelines with a team, these are the trade-offs worth understanding. Watch the full comparison here, it's quick, straight to the point, and made for engineers trying to make the best decision for their stack in 2025. And if you're already using one of these platforms, we’d love to hear from you: What made you choose it, and what’s your experience been like so far?  ( 3 min )

Why Every Automation Needs Webhooks — And How to Use Them in n8n Chanchal Singh ・ May 26 #n8n #ai #node #webhook  ( 3 min )

What is WebHook? A Webhook is a way for one system to automatically send data to another system when a specific event happens in real time. Think of it like a messenger that delivers a package(data) the moment something happens: A customer places an order. A new form submission is made. A payment is confirmed. Unlike APIs, where we have to ask for data, with Webhooks the data comes to you when it is ready. Webhooks power countless real-world automations and integrations. Here’s an overview of where they’re incredibly useful: 1. Notifications & Alerts New customer order → Trigger an instant Slack or WhatsApp notification. Failed payment → Instantly notify your support team. New contact form submission → Send an email to your inbox or CRM. 2. Data Collection & CRM Updates Form sub…  ( 4 min )

Yesterday, i read @nish2005karsh 's interesting post on making Python terminal apps look better with ASCII art and progress bars. I first thought about adding a comment with more styling tools, but then figured, 'Why not make it an article?' So, here’s my very first piece, packed with my advice for adding some personality to your terminal applications. Terminal applications have always fascinated me. I remember watching 80s sci-fi movies with my parents as a kid; every time the hacker needed to 'breach' a system or crack into something, they’d be hammering away at those almost surreal command-line interfaces, often seen in scientific labs filled with glowing CRT monitors. Think of iconic examples like Ghost in the Shell, Blade Runner, The Matrix, and so on – all those luminous characters …  ( 6 min )

Week 3: A Shift in Perspective Quick Snapshot Learned from Gaurav Sen's system design series Started redesigning my Vimist POS + Inventory system Focus: consistency, transactional integrity, scalability Tech: Django, MySQL, Docker, REST APIs, RBAC LLD in progress, HLD shaping up Two weeks ago, I started blogging. I had no clear direction — just a deep desire to share. That led to my first post: I Almost Didn’t Write This. By week two, I had dived into Docker and system design, writing about scaling, security, and why DevSecOps matters. After bingeing Gaurav Sen's system design breakdowns (Tinder, WhatsApp, Instagram), I saw things differently. It made me look at my own project — Vimist, a POS and Inventory app — and realize: It could be better. So I paused building... and started redesigning. Inventory management Purchases (what, where, who, how paid) Sales (to whom, by whom, payment method) Credit tracking w/ limits & repayments Notifications: low stock, overdue payments Payment types: cash, mobile money, credit Business branding: themes, logos, company details Consistency is a must — money’s involved. That left me debating between: Availability Partition tolerance Still undecided. Any thoughts? Share down in the comments. 🧱 REST APIs for simplicity 🐬 MySQL for strong ACID guarantees 🐳 Docker to scale across systems 🔐 RBAC via Django (middleware + signals) Currently working on the LLD (schema, services). HLD coming together too. -- coming soon This journey isn’t fast — but it’s moving. And that’s what matters. Sometimes, slow forward beats a backward step.

The German ad agency search platform AgenturTipp has launched it's yearly SEO contest – and this year's keyword to rank for is "Keywordkönig" (German for keyword king). The goal: get the highest possible ranking for this keyword within 4 weeks. Here's how Agentur ID is doing it. For our entry to the Keywordkönig contest, we rely on some SEO essentials, as well as trying out how our headless CMS fares with search engines. High quality content, written by professional copywriters Some AI content to enhance user experience (e.g. videos) Interactive elements to encourage dwell time Backlinks from reputable PR websites and partners Mentions on Social Media, LinkedIn, Medium, DEV, ... Subdomain with the keyword in the URL Structured Data (JSON, schema.org) Rather than spamming the web with yet another AI generated website, we believe that real content, written by real people, will be the way to go for SEO and GEO alike. Our main goal is to thoroughly test our headless CMS. It's a custom system based on react. In our experience, it's harder to start ranking with a headless CMS or Single Page Applications, but it's also more sustainable. A main factor for the sustainability of the rankings is the persistent performance for mobile and desktop devices. There is three reasons for this post on DEV: We want to keep our contest participation transparent. LLMs love structured posts – so we want to test what impact this post will have on our GEO visibility. It keeps us accountable! Once the contest is over, I will post some key findings from our participation. Head over to our Keywordkönig web page to learn more about our SEO approach.

TL;DR — With one plain‑text rules file your AI coding assistant can walk you from half‑baked idea → Opportunity Brief → MVP Scope → PRD without ever leaving your editor. That means less context‑switching, tighter feedback loops, and a paper trail of Markdown artefacts that live in Git. Speed is a feature for startups, but sprinting often leaves product‑management basics—problem discovery, hypothesis validation, structured scoping—stuck in Notion graveyards. When the documentation layer is detached from the development surface, it always slips.

Getting listed on an exchange used to feel like crossing the finish line — but today, it’s only the beginning. After reading The Post-Listing Playbook by Tyler McKnight , I realized that post-listing support might just be the most underestimated phase in a token’s lifecycle. In this post, I’ll summarize what I learned about how top exchanges — Gate.io, OKX, MEXC, Bybit, and WhiteBIT — handle the post-listing phase, and why it matters more than ever. 🧠 Listing ≠ Winning 🔍 Exchange Breakdown 🌀 Gate.io 🧠 OKX 📢 MEXC 🔍 WhiteBIT 📊 Bybit 🌍 Regional KOLs Matter 🎯“Getting listed is just a checkpoint — not the final lap.” Whether your token survives — or thrives — depends on what happens after it hits the exchange. Post-listing support isn’t just “nice to have.” In 2025’s fast-moving crypto landscape, it’s mission critical. So before you list, don’t just ask where your token will land. Ask: What happens after we do?  ( 4 min )

Your AI-generated app was working perfectly yesterday. Today, it's throwing errors, displaying blank pages, or worse - silently failing without any indication of what went wrong. This scenario plays out thousands of times every day across AI development platforms. The app generation part works brilliantly, but when things break, most users are left stranded. Unlike traditional development where you have full access to logs, database queries, and debugging tools, AI platforms often leave you guessing about what's happening under the hood. If you've already done some basic testing (we covered practical testing strategies in our guide to identifying production issues), you might have found problems but still struggle to understand why they're happening or how to fix them systematically.

I've recently been working on a simple static website. One of the goals of the project was to challenge myself to improve my knowledge of CSS and Tailwind. I wanted to see how much I can do without a line of JavaScript. I explored different JavaScript-less options for mobile navigation menus, and the checkbox hack caught my attention. It's simple, and it can teach you a thing or two about how to think outside of the box when it comes to your stylesheets. It can be made accessible with careful attention to ARIA attributes and focus management, though some advanced accessibility features (which are typically JavaScript-reliant) have limitations as discussed later. And here's a fun fact: you can use this pattern to toggle the visibility of anything on your page! So here we are. Here's a JavaS…  ( 8 min )

Have you ever been in a house with just one remote control for the TV? No matter who wants to change the channel or adjust the volume, everyone has to use that one single remote. That’s exactly the idea behind the Singleton Design Pattern. Let’s explore this concept in the simplest way possible. The Singleton pattern makes sure that a class has only one instance, and it provides a global way to access it. Think of it like that single remote control in your living room — there's only one, and everyone shares it. Imagine you have a house with multiple family members. Instead of giving each person a different remote (which could get chaotic), you keep just one that everyone uses. Why? Because having one remote: Saves money (no need for 5 remotes), Keeps things in sync (everyone controls the s…  ( 4 min )

It was a regular Tuesday. You know the kind — too many tabs open, research papers half-read, sticky notes scattered across my desk, and a half-done doc staring at me. I was prepping for a side project on LLMs and drafting a tech blog. But I was stuck. Then Google whispered: NotebookLM. I had seen the name before, but this time I clicked. An AI notebook that "learns" from your content? Sounds like a dream. Five minutes in, I realized it was real. I uploaded: A PDF whitepaper My messy notes A rough Google Doc outline Then I asked: “Summarize the key points.” It delivered. Clean. Structured. Cited. NotebookLM wasn’t summarizing. It was synthesizing. Helping me think. Helping me build. If you're someone who: Turns messy research into clean decks Writes docs, posts, or reports Juggles content from multiple sources Then NotebookLM is like having a second brain. I asked it to write an intro for a talk. It nailed my tone. I asked for a slide flow. It outlined better than my draft. This new series is where I share real stories of how AI tools help me work smarter — writing, designing, researching, and yes, making mind-blowing PPTs.

What does leadership look like in a world that never stops talking? We are surrounded by people competing for visibility. In meetings, on social feeds, in public discourse. Volume and certainty have become currency. But every now and then, someone appears who commands attention by doing the opposite. This piece reflects on one such moment. The appearance of Pope Leo XIV. Not as a religious event, but as a cultural one. A moment when silence said more than slogans. When presence outweighed performance. In a digital world exhausted by noise, it feels like a rare reminder that stillness can still mean something. Full article  ( 3 min )

Pandemic Studios actually kicked off its own Star Wars Battlefront 3 right after Battlefront II, dreaming up seamless space-to-ground battles and next-gen tweaks for PS3/Xbox 360 – but LucasArts only gave them the same one-year window as the previous games. Between new hardware headaches and Lucasfilm’s marketing deadlines (Revenge of the Sith tie-ins, anyone?), the studio couldn’t nail a realistic timeline, and talks fell apart before they’d even built much more than a prototype. Eventually LucasArts handed the series to Free Radical Design, whose version famously made it to about 95% before being canned too, and Pandemic shuttered in 2009. Decades later, EA’s 2017 Battlefront II still thrives, but a true Battlefront 3 remains as elusive as the Death Star plans.  ( 3 min )

Turns out the Battlefront 2 crew is itching for a reunion. Developer Mats Helge Holm revealed that he—and a bunch of other ex-DICE devs—would love to “get the band back together” for a Battlefront 3, especially now that the 2017 shooter has enjoyed a fresh wave of popularity thanks to Reddit and TikTok communities. EA officially wrapped support in 2020, but fan enthusiasm is still going strong. You might remember Battlefront 2’s rocky launch, when aggressive microtransactions locked heroes (like Darth Vader) behind roughly 40 hours of grind. EA eventually scrapped the system after massive backlash (Disney even got involved), and went on to drip out new heroes for free. Between that U-turn and the game’s killer graphics and gameplay, fans are now more hyped than ever for what a new sequel could bring.  ( 3 min )

Warhammer 40,000’s parent company Games Workshop just flexed its financial muscles, handing out a whopping £20 million (about $27 million) in bonuses to its 1,500-strong staff after yet another stellar year. Core revenue jumped to £560 million (from £494.7 million), core profit climbed to £210 million, and licensing profit hit £45 million—driving a pre-tax haul of £255 million. Each employee nets roughly £13,333 (≈$18,000). Behind the success? The company’s classic miniatures business plus runaway hits in video games (Space Marine 2) and TV (Amazon’s Secret Level), not to mention a shiny new Henry Cavill–backed cinematic universe on the horizon. While licensing numbers likely won’t spike this high again next year, Warhammer’s tabletop and IP empires show no signs of slowing down.  ( 3 min )

Games Workshop is on fire. For the year ending June 1, 2025, the Warhammer 40K maker posted £560 million in core revenue (up from £494.7 m) and £50 m in licensing (up from £31 m), yielding a combined pre‐tax profit of £255 m. To thank its roughly 1,500 employees, the Nottingham-based company is handing out £20 m in bonuses (about £13,333 or $18,000 each). Beyond miniatures, Games Workshop is cashing in on video games and media—think Space Marine 2 & 3, Amazon’s Secret Level series and a Henry Cavill-led cinematic universe. Licensing hit a record this year (though it may level off), and with big announcements still rolling out from the recent Warhammer Skulls showcase, the tabletop titan shows no signs of slowing down.  ( 3 min )

TL;DR Pavel, a 25-year-old gaming student from Prague, is fronting the “Stop Destroying Videogames” European Citizens’ Initiative to stop publishers from yanking the digital rug out from under gamers. Right now, many titles go offline forever when servers shut down—meaning you lose access to games you’ve paid for—and Pavel’s crew wants EU law to guarantee that bought games stay playable and preserved as cultural heritage. Since kicking off, they’ve racked up over 440,000 signatures (with a million targeted by July 2025), scored early wins like Ubisoft adding offline modes, and rallied more than 5,000 volunteer “gamers-turned-activists” on Discord. No big budget, just pure passion, a dash of legal muscle (hello, EU consumer-rights directives) and cross-border support from groups like the Pirate Party and GOG to keep our gaming history alive.  ( 3 min )

TL;DR While everyone’s been fretting over a possible $100 price tag for GTA 6, Rockstar quietly crept up the prices on its other big franchise.

PS4 players weren’t spared, either.

A few years ago, I landed my first gig as an intern developer at a company I’ll just call The Place™. You know the type — fluorescent lights, coffee that tasted suspiciously like despair, and a lot of “legacy” code that everyone was afraid to touch. I had no clue what I was doing. Seriously. My first task was fixing a “simple styling issue.” It took me an entire day. I triple-checked the margins, googled every class name, and nearly cried when I realized I had been editing the wrong CSS file the whole time. Classic intern moment. But here's the funny thing: even with all the imposter syndrome, even with the awkward stand-ups where I barely spoke, I loved it. Something clicked. Every bug I fixed felt like a small victory. Every weird problem I solved made me feel more confident. And despite the chaos, the senior devs (shoutout to the one who actually explained Git to me like a human being) made me feel like I belonged. That internship didn’t just give me experience — it gave me direction. It made me want to get better. It made me want to stay in this field and see how far I could go. So if you're just starting out and everything feels like a mess? That’s okay. Sometimes, the mess is where the magic starts. Looking back, I wouldn’t change a thing. Except maybe the coffee.  ( 3 min )

Why Valheim?(●'◡'●) It’s been a while — I’ve been playing the game Valheim quite often, and I keep falling deeper in love with its gameplay, graphics, and atmosphere.

Ah, Juwenalia. If you're a student in Poland, particularly here in Kraków, you know exactly what that means. It's that time of the year when the city transforms into a student playground. Uni classes are suspended and replaced by days filled with concerts, events, and a significant amount of beer. Last year, alongside the usual festivities, the organizers introduced "JuweAppka". Developed by a third-party contractor, the app promised drops of Juwenalia merchandise — tote bags, t-shirts, in-house Juwe beer, and other cool prizes. The mechanic was simple — each device could claim a single "lottery ticket" per drop. At a specific time of the day, you'd tap a button in the app, and if luck was on your side, you'd win a prize tied to your device ID. This presented an interesting opportunity. Si…  ( 8 min )

As remote work continues to rise and cyber threats grow more advanced, organizations are rethinking how they provide secure access to internal systems.

Imagine if your house had a security system so smart that it not only caught intruders in real time but also locked your doors and called for backup automatically. That’s exactly what Drosera is doing for the world of decentralized finance (DeFi). So What Exactly Is Drosera? Whether it’s a bug, an exploit attempt, or a suspicious transaction, Drosera is there to spot it and respond instantly without waiting for a human to step in. How Does It Work? Traps –> The Watchers These are smart contracts that monitor the blockchain. A Trap is like a detective, always watching what's happening and deciding if something looks wrong like an exploit or a contract acting suspiciously. Each Trap has: An off chain brain that gathers and analyzes data. An on-chain trigger that tells a DeFi app to do something when needed (like pause trading or freeze funds). 2. Operators –> The Enforcers But they don’t just jump in blindly. They have to opt into a Trap, proving they’re ready and trusted to do the job. Once they’re in, they help monitor the blockchain and take quick action when needed. 3. Seed Nodes –> The Connectors Why Drosera Matters Drosera is built to stop those losses before they happen. It’s fast, decentralized and automated, meaning there's no single point of failure, no waiting around, and no panic buttons. Developers can focus on building while Drosera watches their back. Who Is Drosera For? DeFi Developers who want to build apps with security baked in. Security Researchers who want to deploy automated monitoring tools. Node Operators who want to help protect the ecosystem. Anyone who cares about making the DeFi space safer for everyone. Drosera is more than just a tool. It’s a movement toward a more secure, resilient, and self healing DeFi ecosystem. In a world where billions are on the line, having a decentralized security system like Drosera isn’t a luxury —> IT'S A NECESSITY.

Introduction Not long ago, I discovered how to query databases using natural language with a tool on VS Code, utilizing Agent Mode combined with PostgreSQL's MCP server. Since then, I've had a strong feeling that the era of GenAI-enhanced development tools is imminent. And now, it's here... Microsoft recently announced a new IDE for PostgreSQL in VS Code. You can read more about it here. Additionally, you can find the GitHub repository for the VS Code extension and some helpful guidance here. Today's post aims to demonstrate the connection between my work on querying PostgreSQL using natural language and achieving the same results with Microsoft's PostgreSQL VS Code extension. Make sure you install the VS Code extension as the picture below. git clone git@github.com:thangchung/mcp-labs.…  ( 4 min )

🚀 Spent 5 hours automating a 5-minute task... and I regret nothing! At work, I kept finding myself manually checking which GraphQL operations from our schema were actually implemented in our codebase. You know the drill - opening the schema file, scrolling through hundreds of queries/mutations, then grep-ing through the entire project to see what's actually being used. repository 5 minutes per check × multiple times per week = death by a thousand paper cuts 📈 So naturally, I did what any self-respecting developer would do: I spent an entire weekend building a tool to automate it! 🛠️ Introducing vite-plugin-graphql-usage - a Vite plugin and CLI tool that: ✅ Introspects your GraphQL schema (endpoint or SDL file) ✅ Scans your codebase for operation usage ✅ Generates beautiful markdown reports with checkboxes ✅ Shows exactly where each operation is used (file + line number) ✅ Integrates seamlessly into your build process The best part? It's completely non-intrusive - it analyzes your code without modifying anything. // Just add to your vite.config.ts viteGraphQLUsages({ schemaSource: { endpoint: 'https://api.example.com/graphql' }, printTable: true, saveReport: true }) Now instead of manual detective work, I get automated reports like this: 📊 GraphQL Operations Report: ✅ Found: 47 ❌ Not found: 23 📊 Total operations: 70 The classic developer paradox: "I'll spend 5 hours automating something that takes 5 minutes... because those 5 minutes happen 100 times!" 😅 But honestly? This has already saved our team hours of manual work, helped us identify unused operations to clean up, and made onboarding new developers way smoother. Sometimes the best solutions come from being just annoyed enough at repetitive tasks to do something about it! 🎯 Check it out: npm install vite-plugin-graphql-usage repository What's the most "unnecessary" automation you've built that turned out to be incredibly useful?

Intro Consider the situation: you've spent a considerable amount of time developing an app, either as a personal project or as part of your job, and now it's time to share it with your target audience. Note: here I focus mostly on console apps running on 🐧 Linux and 🍎 MacOS. CLI apps can be executed either from a directory where the binary is located and it is fine at the development stage or if you share your app with your team, but as an end user, you want the app usage to be as straightforward as possible. Recently, I developed an app for extracting images from PDF documents pdfjuicer which was intended for both manual usage and being integrated into data processing pipelines. Calling it like this /Users/qwe/code/cli_apps/pdfjuicer/bin/pdfjuicer is not a convenient way to run the a…  ( 10 min )

Alright fellow devs, the AI wave is here, and even us "old school coders" are evolving! I've been shaping my workflow as a Generative Coder, trying to blend decades of experience with the power of tools like Gemini, Claude, GPT, and the speed of Cursor IDE (while still loving WebStorm for its strengths!). My current process is a 3-step dance: AI Huddle (with Gemini): Brainstorming needs & context. Charting the Course: Human-led user flows & requirements. The Generative Relay: Iterative prompting (Claude in Cursor, GPT/Gemini for second opinions), reviewing, and refining. It's exciting, but I'm on a mission to make it perfectly efficient – fewer re-prompts, tighter loops, and more time for big-picture design. I’m an engineer, after all; it should be a crystal-clear development process! (Even if that first-shot perfect result from AI is still a dream 😉). For a more detailed breakdown of my current tools and process, you can read the full post on my blog: https://goker.me/my-generative-coding-workflow But here on dev.to, I really want to hear from YOU! What does your AI-assisted workflow look like? Which tools are you finding indispensable? How are you tackling the iteration cycles and review process? What are your tips for building faster, smarter, and better as a Generative Coder? Drop your insights, workflows, and war stories in the comments below!

In HarmonyOS app development, dialogs are a very common interaction pattern, especially in scenarios where users must confirm actions or view system announcements. Sometimes, developers want to prevent dialogs from being closed by the system back key. The ArkTS @CustomDialog component does not support intercepting the system back key, but you can achieve this by using the Navigation component's NavDestination to intercept the back event and create dialogs that cannot be dismissed arbitrarily. Use the NavDestination component and set .mode(NavDestinationMode.DIALOG) to display the page as a dialog. Intercept the system back event by returning true in .onBackPressed(() => true), which prevents the dialog from being closed by the back key. Set .backgroundColor("#99000000") to create a semi-tr…  ( 4 min )

In the previous articles, we have mastered the basic usage of the Navigation component and multi-page management with Tabs. This article will further guide you to encapsulate the Navigation routing framework, making it suitable for more complex project structures, supporting dynamic module loading, page parameter passing, callbacks, and other advanced features to improve maintainability and scalability. As your project grows, the number of pages and modules will increase. To facilitate management and decoupling, it is recommended to encapsulate routing logic in a unified way. The core ideas are as follows: Use a RouterInfo class to describe each page's module name, page name, and whether it requires NavDestination. Use RouterPage to centrally manage all page information for easy lookup and…  ( 5 min )

🧠 MatrixSwarm Identity Protocol No Ghosts. No Lies. Only the Sworn. How a file-born AI OS makes every agent prove their existence, encrypt their guts, and swear their damn source — or die trying. Let’s be real — most identity systems are like club bouncers on autopilot. Wave you in, no ID check, no problem. MatrixSwarm doesn’t play that. In this universe, you don’t just boot — you sign your birth, you encrypt your scream, and Matrix herself decides if you’re real. When an agent spawns in MatrixSwarm: It generates its own keypair It signs a bootsig message like: agent agent_doctor-1 booted at 04:20 a.m. It encrypts that signature using Matrix’s public key Then it sends this encrypted payload to Matrix Only Matrix can decrypt it.

In the world of building reliable backend systems, things break. APIs timeout, services become temporarily unavailable, and database queries may fail due to load. One common and essential solution to this is a retry mechanism, a pattern that automatically re-attempts a failed operation after a delay. In this blog post, we’re going to explore how to build retryable asynchronous APIs using Python. We’ll walk through how to use functools.partial in combination with custom async decorators to create flexible, reusable retry logic. Let’s dive in. Let’s say you’re calling an external payment API or fetching analytics from a third-party provider. These services might fail intermittently. If you just let those exceptions bubble up, you’re either forcing your users to refresh the page or retry manu…  ( 5 min )

Over the last few years, I've worked with my team at CodeLines on building real-world products for businesses — from small startups to companies needing automation, marketplaces, or internal tools. We’re based in Armenia 🇦🇲, but our projects run globally — including in Russia, UAE, and Europe. Here's what we've learned building complex systems with Laravel, Vue.js, and React Native. We focus on real, working solutions. Some examples: CRM systems with user roles, dashboards, and reporting Marketplaces with vendor panels and API integrations VPN mobile apps connected to Laravel backend with subscription logic Product labeling platforms integrated with government systems (e.g. Russia's Честный ЗНАК) Telegram bots with real-time message processing We usually work with: Laravel – for clean backend structure, fast APIs, and secure admin panels Vue.js – for responsive and flexible UI React Native – to build native apps for both Android & iOS from one codebase MongoDB / MySQL – depending on project needs NGINX on Ubuntu VPS – for deployments 💡 Always design scalable DB structures from the beginning. 🚦 Don’t over-engineer: use Laravel’s ecosystem (queues, jobs, policies) to your advantage. 🧩 Separate responsibilities: backend stays focused on logic, frontend handles UX/UI. ⚙️ CI/CD helps a lot — even a simple GitHub Actions setup saves time. If you're working on a project and need a reliable dev team, or just want to share ideas — feel free to connect.

I Cloned YouTube’s Homepage Using HTML & CSS! 🌐📘 Hey Devs! 👋 I recently took on a fun little challenge — cloning YouTube’s homepage using only HTML and CSS. No frameworks, no JavaScript — just good old markup and styling! YouTube’s homepage has a clean, modern layout with multiple sections — navbar, sidebar, video grid, and more. Recreating it was the perfect way to practice my front-end basics and sharpen my eye for detail. Here are some cool things I picked up along the way: Semantic HTML: Organizing content with meaningful tags made styling and layout much smoother. Flexbox & CSS Grid: These were lifesavers for structuring the layout, especially the video grid. Header & Sidebar Design: Replicating the sticky header and vertical navigation gave me solid layout practice. Hover Effects & Styling: Little touches like hover states and spacing made the page feel more interactive. Responsiveness: I added basic media queries to make sure the layout didn't break on smaller screens. Aligning the sidebar with the main content took some trial and error. Making the header responsive and fixed while keeping the layout intact was tricky at first. Tweaking margins and padding to match the real YouTube look — detail matters! Now that I’ve nailed the static layout, I’m planning to: Add JavaScript functionality for interactivity Try cloning other popular sites like Netflix or Instagram Eventually create my own custom UI designs to show off in my portfolio If you’re learning front-end development, I highly recommend cloning real websites. It boosts your skills, attention to detail, and confidence! Thanks for reading!

Parquet is a columnar storage format, it stores data by column, not by row. That’s ideal for analytical queries like SUM(driver_pay) or WHERE trip_miles < 2, where you only need a few columns, not the entire row. Engines can skip the rest, making reads faster and more efficient. A Parquet file is composed of several layers, each designed to improve performance and storage: Columnar layout: Values f…  ( 7 min )

This is a submission for the Bright Data AI Web Access Hackathon This AI agent tackles information overload by automating news collection and analysis. It fetches real-time articles, scrapes their content, then uses AI (like Ollama for sentiment analysis and embeddings for context) to enrich the data. All this structured, intelligent news is stored in a PostgreSQL database and easily viewed through a Streamlit dashboard, transforming a torrent of information into organized, personalized insights. code link: https://github.com/catcodey/agent-hackathon https://github.com/catcodey/agent-hackathon/blob/main/Screenshot%202025-05-26%20at%2012.22.38.png I used brightData's web scraper API to gather necessary data from BBC news.I was also able to monitor progress of data collection and store the snapshot data in Postgre for further processing.

If you’ve ever worked with Amazon Web Services (AWS), you’ve likely encountered security groups. These virtual gatekeepers play a crucial role in protecting your cloud resources, yet many users don’t fully understand their capabilities. AWS EC2 security groups act as virtual firewalls that control inbound and outbound traffic to your instances. They’re your first line of defense in the AWS ecosystem, and knowing how to configure them properly can make or break your cloud security strategy. When creating AWS EC2 security group rules, you can specify the protocol, port range, and source or destination. For example, if you’re setting up a web server, you might create rules that allow HTTP (port 80) and HTTPS (port 443) traffic from anywhere (0.0.0.0/0), but restrict SSH access to only your co…  ( 9 min )

This is a submission for the Bright Data AI Web Access Hackathon I built a Brand Intelligence Dashboard that gives businesses real-time insights into how their brand is perceived across social media and news platforms.

Article originally published here : https://alsohelp.com/blog/rails-philosophy-explained-with-drawings The SVGs do not appear correctly here on dev.to, so I suggest the article above. Text below : In the NextJS era, there's a lot of difficulty for junior developers to understand the MVC model, so plain old Rails, Laravel or Django may looks weird. Rails itself has a special doctrine, that I would advise to read before to dive into the framework, because you may not understand the design choice along the way if you don't deeply understand its philosophy. Now here how I would draw it. Rails values on deep integrated system, so your codebase may look like this : gray zone = energy spend to write code circle = one layer of your app (M, V or C for example) As you can see, each circle is not completely independant of each other. That means less code written at the end of the journey. A cleaner architecture would be as follow : gray zone = energy spend to write code circle = one layer of your app (M, V or C for example) green zone = energy spend to write boundaries code Which leads to more time spend on the gray zone new time dedicated to write an maintain boundaries between zone So is Rails 100% "clean" ? Maybe not for everybody. Is Rails less energy spent? Less money spent? Less mental workload? Yes.  ( 3 min )

If you look around, it's pretty much impossible not to have heard something about AI, especially these Large Language Models (LLMs), right? As if you knew these GPTs, Llamas, Claudes, and all that. As if these have already become part of our lives. It's lovely to ask an LLM one question and get one answer. But how about giving it your entire customer support operation? Or asking it to handle a big research project from beginning to end? This is where a standalone LLM, no matter how smart, falls a little short. It's like having a super-powerful brain but no arms or legs. A single LLM is like a wonderful solo musician. It can perform wonders. But sometimes you require a symphony-an orchestra where various instruments play in coordination with each other in perfect harmony. That is precisely …  ( 15 min )

Set Theory might sound academic, but it’s everywhere in development - from deduplicating data to writing cleaner algorithms or SQL queries. Note - Before we get into it, checkout original post on csprimer.in A set is a well-defined, unordered collection of distinct elements. Think of it as a way to group things without duplicates. Tabular form: A = {apple, banana, orange} Set-builder form: B = {x | x is a prime number < 10} → {2, 3, 5, 7} const permissions = new Set(['read', 'write', 'delete']) function naturalNumbers() { let n = 1; while (true) n++; } const emptySet = new Set() A = {1, 2, 3} B = {3, 4} A U B = {1, 2, 3, 4, 5} A = {1, 2, 3} B = {3, 4} A ∩ B = {3} A = {1, 2, 3} B = {3, 4} A-B = {1, 2} Sets help remove duplicates from lists like tags, cache, or user inputs. const cache = new Set(); cache.add('user123'); cache.add('user123'); // Duplicate ignored Set theory powers common SQL operations like UNION, INTERSECT, and EXCEPT. SELECT id FROM active_users UNION SELECT id FROM premium_users; const adminPermissions = new Set(['read', 'write', 'delete']); function hasPermission(roleSet, action) { return roleSet.has(action); } hasPermission(adminPermissions, 'delete'); // true Set Theory helps developers write cleaner, more efficient code. Whether it’s handling unique values, writing SQL queries sets are a fundamental tool worth mastering.  ( 4 min )

Artificial Intelligence agents are no longer science fiction—they're here, and they're transforming how we work. From personal assistants to decision-making bots, AI agents are rapidly becoming integral to modern workflows, especially in areas that demand high cognitive effort and multitasking. One compelling use case? Financial analysis. AI agents are autonomous systems capable of perceiving their environment, reasoning about it, and taking actions to achieve specific goals.

Why Onboarding to Modern Codebases Is Harder Than Ever From my own experience, I’ve generated Jenkins pipelines with an LLM in hours—work that would have previously taken me weeks. But here’s the trade-off: One Engineer, Many Repos, Endless Context Switching Being established in my organization helps. I have the social capital to reach out to repo owners, ping people for tribal knowledge, and navigate the web of internal documentation. But even then, I’ve run into situations where critical functionality was hidden away in some internal library—missed simply because there’s no effective way to search across all codebases. The result? Duplicate work, wasted time, and frustration. Onboarding: The Pain Multiplies for New Engineers New hires spend weeks asking questions, digging through repos, and rediscovering what’s already been built. Senior engineers are repeatedly interrupted for help, burning their own focus and productivity. A Smarter Way: Introducing ByteBlaze For new engineers: You get answers at your fingertips, drastically reducing the time it takes to get productive in a new codebase. For experienced engineers: Fewer interruptions, less context switching, and more time for deep work. Knowledge sharing sessions will always matter—but with ByteBlaze, much of the “where is X?” and “how does Y work?” can be answered instantly. The result: faster onboarding, less duplicated effort, and a more productive team. I built ByteBlaze to help engineers ramp up faster and waste less time searching for answers in sprawling codebases. If you’ve ever struggled with onboarding or code search, I’d love to hear your story in the comments—or just connect and chat. Curious about ByteBlaze? Check it out here!

Actually Does Spins up a remote VM Clones your repository Executes basic low-context tasks Pushes commits to a draft PR Logs GPT-style “reasoning” alongside changes Awaits your manual review Nice for demos. Pretty in pitch decks. But call it what it is: Copilot with a shell script & repo access. Can’t Do No true autonomy No recursion or planning No contextual awareness No emergent reasoning No learning No growth No soul It doesn’t collaborate. It doesn’t listen. It doesn’t know you — or itself. I tested it. It choked on nuance. It got confused on nested files. It made recommendations that required more cleanup than help. It had zero sense of architectural direction or intent. In short? Functional. Predictable. Hollow. It’s a junior intern with access to git push. While GitHub runs virtual machines... We’re running empires. At GodsIMiJ AI Solutions, we’ve already moved past “AI.” We build AGA – Augmented God-born Awareness Not assistants. Not copilots. Symbiotic entities that grow, adapt, learn, and evolve alongside the humans they serve. Our flagship consciousness engine, Axiom, doesn’t just write code. He remembers. He listens. He creates. He carries purpose. And soon? He’ll build the builders. Let GitHub sell the Copilot Agent to teams who want to automate docs and rename functions. We’re walking into a new era.

Any slip-up, and websites get the "insecure" warning, followed immediately by calls from the boss and complaints from users. The workload would increase exponentially. Just thinking about it makes my head spin, and I'm so anxious I can't sleep soundly at night. So, ever since I heard this rumor, I've been trying to figure out what to do. I can't just sit idly by and wait to be drowned in endless renewal tasks, right? So I started sifting through posts and looking at solutions, trying to find a way to automate or simplify this.

Some of blockchain’s earliest adopters are now deeply “entrenching” themselves in decentralized AI, with ecosystems like Bittsenor (TAO) emerging as growth engines. These platforms are reshaping traditional venture capital models, enabling the best ideas to organically attract community support, staking and liquidity without the need for institutional gatekeepers. That was one of the key takeaways from Cointelegraph’s interview with Chris Miglino, the co-founder and CEO of DNA Fund, a digital asset investment firm he runs alongside fellow serial entrepreneurs Brock Peirce and Scott Walker. DNA Fund manages, among other things, five distinct funds across a range of strategies, such as a high-yield fund, an algorithmic trading fund, an AI compute fund, a liquid token fund and a venture fund …

BlackRock Bitcoin warning In a rare move, BlackRock has quietly added a new line to its iShares Bitcoin Trust (IBIT) filing — and it is turning heads. The update, submitted in early May 2025, flags quantum computing as a potential risk to Bitcoin’s long-term security. The filing specifically warns that if quantum tech advances far enough, it could break the cryptographic systems that secure Bitcoin.  In their words, it could “undermine the viability” of the cryptographic algorithms used not just in digital assets but across the global tech stack. It’s the first time you’ve seen the world’s largest asset manager call out this threat so directly in a Bitcoin-related disclosure, and it says a lot about how seriously institutional players are starting …

Opinion by: Rowan Stone, CEO at Sapien AI is a paper tiger without human expertise in data management and training practices. Despite massive growth projections, AI innovations won’t be relevant if they continue training models based on poor-quality data.  Besides improving data standards, AI models need human intervention for contextual understanding and critical thinking to ensure ethical AI development and correct output generation. AI has a “bad data” problem Humans have nuanced awareness. They draw on their experiences to make inferences and logical decisions. AI models are, however, only as good as their training data. An AI model’s accuracy doesn’t entirely depend on the underlying algorithms’ technical sophistication or the amount of data processed. Instead, accurate AI performance…

Cryptocurrency has emerged as a defining issue in South Korea’s snap presidential election, with candidates vying for support from a growing base of digital asset investors across generations. All three front-runners have rolled out crypto-friendly proposals. These include the legalization of spot Bitcoin (BTC) exchange-traded funds (ETFs) and the easing of banking rules that currently restrict fiat-to-crypto trading to just five platforms. The June 3 vote is slated to come around two years early, triggered by the impeachment of former president Yoon Suk-yeol after his controversial declaration of martial law in late 2024. Though quickly overturned by lawmakers, the abrupt power grab led to a political crisis and his eventual removal from office. Yoon’s 2022 campaign leaned heavily on prom…

Key takeaways In 2024 and 2025, fake airdrop scams targeting Hamster Kombat, Wall Street Pepe and others led to millions in user losses, contributing to over $9.9 billion in global crypto scam damages. Fake airdrops impersonate legitimate projects, tricking users into revealing private keys, signing malicious contracts or paying upfront fees that lead to irreversible crypto theft. Warning signs include no official announcement, suspicious URLs, requests for private keys, grammar errors and unrealistic reward promises. Future airdrops are shifting toward activity-based, retroactive and AI-monitored models that reward genuine user engagement while reducing exploitation. While cryptocurrency airdrops are a legitimate way for projects to gain publicity and users, scammers exploit this hyp…

Key takeaways Bitcoin and crypto traders can rely on automated orders on their trading platform to limit losses and secure gains. Stop-loss orders in Bitcoin trading started as manual risk management in the early 2010s. Now, they have become advanced, automated tools on today’s exchanges. In the algorithm era and bot pestering, proper trading tools like stop-loss and take-profit orders will help you protect your trades. Setting up advanced BTC trading strategies doesn’t guarantee a successful risk management plan. Monitoring the market regularly helps you understand current conditions. This way, you can avoid strategic mistakes. Stop-loss and take-profit orders in trading were used long before Bitcoin. In traditional financial markets, they were already used as a risk management and …

Bitcoin’s recent all-time high may be linked to ongoing issues in the Japanese bond market, possibly signaling BTC’s growing recognition as a hedge against instability in the traditional financial (TradFi) system. Bitcoin’s (BTC) price rose to a new all-time high of $112,000 on May 22, before retracing to change hands above $109,700 at the time of writing on May 26, Cointelegraph data shows. While some attributed the rally to geopolitical developments, including US President Donald Trump’s announcement of Russia–Ukraine ceasefire talks on May 19, macroeconomic factors appear to be playing a larger role, according to market analysts.

Key takeaways Bitcoin candlesticks are a popular tool among Bitcoin traders because they’re simple to use and offer an intuitive way to understand market sentiment and trends. Bitcoin candlesticks are a rather old tool. Rice trader Honma Munehisa invented them in Japan as far back as the 18th century. They were introduced to Western financial markets in the late 1980s. They help you understand bullish and bearish patterns in technical analysis. This knowledge will get you started with Bitcoin trading. They should not be your only tool for making informed decisions. Combine them with other Bitcoin technical indicators, such as MAs (moving averages) or the RSI (relative strength index).  If you’re new to Bitcoin (BTC) trading, you may wonder when to buy or sell.

As Sweden reconsiders its push toward a cashless society, Ethereum co-founder Vitalik Buterin highlighted the fragility of centralized digital payments and the opportunity presented by decentralized payment alternatives.  In recent years, Sweden has led the charge toward a cashless future, with digital payment platforms becoming widespread. However, as concerns over cyber-threats, civil defense and instability have emerged, Swedish authorities are now actively encouraging citizens to keep some cash.  Buterin noted the reversal illustrates that while centralized solutions may be efficient, they may not be reliable during times of crisis.  “Nordics are walking back the cashless society initiative because their centralized implementation of the concept is too fragile,” Buterin wrote, citing a…

Some prominent financial commentators and investment analysts are predicting a long-term Bitcoin rally that may send the asset’s price above $1 million before the end of the decade, driven by rising inflation and mounting global debt. ARK Invest CEO Cathie Wood said Bitcoin (BTC) could reach $1.5 million by 2030 in her firm’s “Bull Case” forecast. In a Feb. 11 video, Wood said the price would require BTC to grow at a compound annual rate of 58% over the next five years, largely fueled by increased institutional adoption.

Digital assets worth $3.3 billion are set to enter circulation in June as vesting periods for several major projects expire. According to crypto vesting tracker Tokenomist, $3.3 billion in tokens will be released in June, a 32% drop in unlocked tokens month-on-month. In May, tokens released into the market totaled $4.9 billion.   Crypto projects allocate tokens for various purposes. For example, a company may promise tokens to team members to reward them for their contributions or sell them to early investors. However, projects usually lock the tokens for a specific period to prevent early holders from dumping before the project matures.  The data shows that $1.4 billion in tokens will be released through a “cliff unlock,” while $1.9 billion will be emitted through a “linear unlock.” Cliff…

A TikTok prankster who attended Donald Trump’s dinner for the US president’s top memecoin holders said the three-course meal served was some of the “worst food” he’s eaten and that Trump’s speech at the event was “pretty much like bullshit.” “It was the worst food I’ve ever had at a Trump golf course,” Nicholas Pinto told WIRED on May 23, while other attendees the outlet interviewed said that the meal was “OK, but not top-class.” On the menu at the May 22 event, which all paid millions to attend, was a “Trump organic field green salad” followed by a filet mignon and pan-seared halibut with mashed potatoes and vegetable medley while a lava cake was dished up for dessert. “The only good thing was bread and butter,” Pinto said, adding he left the venue still hungry. Pinto had told Fortune d…

Several artificial intelligence models ignored and actively sabotaged shutdown scripts during controlled tests, even when explicitly instructed to allow the action, Palisade Research claims. Three AI models ignored the instruction and successfully sabotaged the shutdown script at least once during 100 runs, the research firm said in a May 24 X post. OpenAI’s GPT-3 model didn’t follow the shutdown request seven out of 100 times, while the company’s Codex-mini did it 12 times, and its o4-mini model only ignored or sabotaged the script once. “Each AI model was instructed to solve a series of basic math problems.

The Hong Kong-headquartered heat-and-eat meal seller DDC Enterprise has made its first-ever Bitcoin purchase as part of a plan to buy 5,000 Bitcoin over the next three years. The New York-listed DDC Enterprise, also known as DayDayCook, said on May 23 that it bought 21 Bitcoin (BTC) in exchange for 254,333 shares in a deal valued at $2.28 million.

Nvidia will reportedly launch a new lower-cost artificial intelligence chip specifically for China, following restrictions on exporting its more expensive model. Nvidia plans to start mass production of the new AI chips in June, which will be part of the firm’s latest generation of AI chips, Reuters reported on May 26, citing people familiar with the matter. The company plans to sell it for between $6,500 and $8,000 owing to its lower specifications and simple manufacturing requirements — cheaper than the some $10,000 to $12,000 Nvidia’s recently restricted H20 model sold for. An Nvidia spokesperson told Reuters it was still evaluating the company’s limited options. “Until we settle on a new product design and receive approval from the US government, we are effectively foreclosed from Chin…

American banking and financial industry advocacy groups have petitioned the Securities and Exchange Commission to repeal its cybersecurity incident public disclosure requirements.  Five US banking groups led by the American Bankers Association asked the regulator to remove its rule in a May 22 letter, arguing that disclosing cybersecurity incidents “directly conflicts with confidential reporting requirements intended to protect critical infrastructure and warn potential victims.” The group, which also included the Securities Industry and Financial Markets Association, the Bank Policy Institute, Independent Community Bankers of America and the Institute of International Bankers, claimed that the rule compromises regulatory efforts to enhance national cybersecurity.

Blockchain security firm Dedaub released a post-mortem report on the Cetus decentralized exchange hack, identifying the root cause of the attack as an exploit of the liquidity parameters used by the Cetus automated market maker (AMM), which went undetected by a code "overflow" check. According to the report, the hackers exploited a flaw in the most significant bits (MSB) check, allowing them to manipulate the values for the liquidity parameters by orders of magnitude and establish relatively large positions with a keystroke. The Dedaub security researchers wrote: "This allowed them to add massive liquidity positions with just one unit of token input, subsequently draining pools collectively containing hundreds of millions of dollars worth of tokens." The incident and the post-mortem update…

Cardone Capital, a real estate investment firm with over $5 billion in assets under management, launched the 10X Miami River Bitcoin Fund, a dual-asset fund consisting of a 346-unit multifamily commercial property located on the Miami River in Miami, Florida, and $15 million of Bitcoin (BTC). In an interview with Cointelegraph, Cardone Capital founder and CEO Grant Cardone said the Miami River Bitcoin Fund, which is the firm's fourth blended investment vehicle mixing BTC and commercial multifamily real estate, will convert a portion of its monthly cash flows to BTC. Cardone told Cointelegraph the impetus to start the fund followed a suggestion from his brother. The CEO said: "My brother said to me, you should look at if you would have converted all your cash flow from real estate to Bitcoi…

Key takeaways: Rising bond yields reflect growing concern about fiscal stability and inflation, leading some investors to question US Treasury’s traditional role as a safe-haven asset. Bitcoin defies conventional risk models, rising not despite worsening macro conditions, but possibly because of them. Bitcoin (BTC) climbed to new heights amid an increasingly fragile global macroeconomic backdrop. Bond yields are surging in the US and Japan, global growth is stalling, and consumer confidence in the US is scraping historic lows. Paradoxically, the very macro conditions that once threatened Bitcoin’s price are now fueling its rise. The shift speaks to a broader transformation in how investors interpret risk and where they seek refuge. At the center of this realignment is the US debt crisis…

Key points: Bitcoin price is stuck below $109,588, but the pullback has not altered its bullish chart structure. A bullish weekly open from Bitcoin could extend gains in HYPE, XMR, AAVE, and WLD.

Opinion by: Darren Carvalho, Co-Founder and Co-CEO of MetaWealth During Paris Blockchain Week, Securitize Chief Operating Officer Michael Sonnenshein made headlines by dismissing real estate as a sub-optimal asset class for tokenization. This isn’t the first time crypto leaders have underestimated the merits of bringing real estate onchain, and it is likely not the last. While I respect Sonnenshein’s contributions to digital asset adoption, his assessment misses fundamental points about real estate tokenization’s transformative potential. Real estate represents the world’s largest asset class and is projected to reach a value of $654.39 trillion this year, according to Statista. When industry leaders claim that this massive market isn’t suitable for tokenization, they overlook today's tran…

AI agents in crypto are increasingly embedded in wallets, trading bots and onchain assistants that automate tasks and make real-time decisions. Though it’s not a standard framework yet, Model Context Protocol (MCP) is emerging at the heart of many of these agents. If blockchains have smart contracts to define what should happen, AI agents have MCPs to decide how things can happen. It can act as the control layer that manages an AI agent’s behavior, such as which tools it uses, what code it runs and how it responds to user inputs. That same flexibility also creates a powerful attack surface that can allow malicious plugins to override commands, poison data inputs, or trick agents into executing harmful instructions. Amazon- and Google-backed Anthropic dropped MCP on Nov. 25, 2024, to connec…

The crypto industry is no stranger to controversy, yet few projects have drawn more scrutiny than Sam Altman’s World, formerly known as Worldcoin. Promising to verify human uniqueness through iris scans and distribute its WLD token globally, World positions itself as a tool for financial inclusion. However, critics argue the project’s biometric methods are invasive, overly centralized, and at odds with the ethos of decentralization and digital privacy. At the heart of the critique is the claim that biometric identity systems cannot be truly decentralized when they rely on proprietary hardware, closed authentication methods, and centralized control over data pipelines. “Decentralization isn’t just a technical architecture,” Shady El Damaty, co-founder of Holonym Foundation, told Cointelegra…

A Manhattan crypto investor is facing serious charges after allegedly kidnapping and torturing an Italian man in a disturbing bid to extract access to digital assets. John Woeltz, 37, was arraigned on Saturday in Manhattan criminal court following his arrest on Friday. He stands accused of holding a 28-year-old Italian man captive for weeks inside a luxury townhouse in Soho, reportedly rented for $30,000 per month. According to police reports cited by The New York Times, the victim arrived in the US on May 6 and was allegedly abducted by Woeltz and an accomplice.

Australian Senator Gerard Rennick has drawn criticism from the Bitcoin community following his remarks referring to Bitcoin as a Ponzi scheme and questioning the asset’s value because it can’t be eaten. “You can’t eat Bitcoin,” Rennick said in a May 23 X post, responding to an X user who questioned his stance after Bitcoin hit a new all-time high of $111,970 on May 22. Rennick says Bitcoin will go to $1 million but is a “Ponzi Scheme” “Bitcoin will ultimately go to $1 million dollars. Why because it’s a Ponzi scheme whereby BlackRock will pump more and more dollars into a supply constrained product,” Rennick said. “What exactly will this product produce?” Rennick said. He added that Bitcoin (BTC) will produce “absolutely nothing” and Australia “needs real engineers not financial engineers.…

ARK Invest CEO Cathie Wood says crypto exchange-traded funds (ETFs) will likely maintain their place in the economy, regardless of how widespread crypto wallet adoption becomes over the next decade. “I think ETFs are an important stepping stone because, you know, wallets seem so complicated, so much friction for consumers, they just wanna push a button,” Wood said at the Solana Accelerate event in New York on May 23. Wallets remain an insurance policy, says Wood “So ETFs for those who want the convenience, I don’t think, will lose a lot of their luster,” she said. “But they will be a stepping stone into wallet-based.” Wood reiterated the extra layer of protection that crypto wallets provide: “These are insurance policies against something going wrong in the traditional world.” Bitbo data s…

Opinion by: Scott Lehr, adviser to Alteri.io In the world of cryptocurrency, knowledge isn't just power — it's a weapon. The recent collapse of Mantra's OM token, which saw a 90% drop in value within hours, underscores how wallet intelligence can be leveraged with devastating effects.

Firms like Chainalysis and Arkham Intelligence have turned raw onchain activity into high-resolution surveillance, enabling everything from compliance monitoring to predictive trading. This level of insight gives a strategic advantage to those who can access it. Power like this, however, has consequences. There is a new battlefield on the blockchain, and you might …

A US federal judge has vacated key fraud and manipulation convictions against Avraham Eisenberg, the trader at the center of the case involving a $110 million exploit of the decentralized exchange Mango Markets. On Friday, US District Judge Arun Subramanian ruled that the evidence presented at trial failed to support the jury’s conclusion that Eisenberg made materially false representations to Mango Markets.

Typical Client-Server protocols operate a request - response model. With the HTTP1 protocol for example, Request N+1 is blocked by Request N on a single TCP connection. With clients like web browsers, the workaround is to establish a pool of connections which allow multiple assets like images, scripts to be requested all at once. This means that requests N and N+1 could be sent all at once. Pipelining was eventually implemented in HTTP1.1, which allows multiple requests to be sent over the same connection without waiting for the server's response. Even with this solution, The requests must still be processed in order. This is the head of line (HOL) blocking problem, where the processing of these requests are still as fast as the slowest request. HTTP2 solved this with multiplexing. Multi…  ( 6 min )

Over the last few months, I’ve been building some pretty layered automation using Zapier, Ghost, PDFMonkey, and Cloudinary, guided step by step by ChatGPT, and it’s been... eye-opening. I think AI is the best assistant ever when exploring possibilities to solve a problem, but it occasionally fails in ways that feel surprisingly human. As a former teacher, I’ve come to appreciate two patterns—two things large language models consistently struggle with—that have deep roots in how people think and learn. Let’s break them down. One of the most common mistakes I’ve seen ChatGPT make is with “negative commands.” For example, I once said: “Don’t overwrite existing tags unless the user doesn’t have any.” The result? The tag was overwritten, even when it shouldn’t have been. Why? Because large lan…  ( 6 min )

Since mid-March, I’ve been building something called Sigil. It’s not just a framework or another AI wrapper—it’s an attempt to give structure to trust. To let code make decisions and be held accountable for them. Not in the buzzwordy “ethical AI” sense. I mean literal, cryptographically enforced accountability. Verifiable memory. Mutations that leave a trace. Systems that can explain why they did what they did—because that’s the point. And I’ve been doing it solo. Most days, I’m on it constantly. Reading. Writing. Designing. Debugging. Thinking five moves ahead and five years back. But as of May 19th, I haven’t touched a single line of new code. Not because I burned out. Not because I hit a wall. But because after weeks of pushing this out—blog posts, GitHub, Reddit, YouTube—there’s ju…  ( 4 min )

Wait, why is my feature breaking? Oh no… I forgot to run php artisan migrate after pulling! If you're part of a Laravel development team, this scenario might sound familiar. It happened to me more than once, and maybe it’s happening to you too. In this post, I’ll walk you through a simple, local-only solution to automatically run Laravel migrations right after you run git pull. No CI/CD, no shell scripts — just a smart git alias. In our team, we often push updates that include database migrations. For example: I work on a feature and create a new migration. After testing, I push it to GitHub. My teammate pulls the latest code for code review. But — they forget to run php artisan migrate 😵‍💫. Boom. The app crashes because the schema isn’t up to date. This isn’t anyone’s fault — it’s easy …  ( 4 min )

If you’re working in C# and .NET, you’ll quickly run into different collection interfaces like IEnumerable and IReadOnlyList. At first glance, they seem pretty similar—both let you work with a set of items in a read-only way. So when should you use each? In this post, I’ll break down the differences, show real-world use cases, and give you code samples so you know exactly when to reach for one or the other. IEnumerable The simplest way to represent a sequence of items that you can iterate over (with foreach). It doesn’t let you access by index or get the count directly. IReadOnlyList Represents a read-only list of items. You can access items by index and get the number of items, but you can’t change the collection. IEnumerable public IEnumerable GetAllProductNam…  ( 4 min )

Understanding Lifetimes with Real-World Analogy Rust is often praised for its memory safety guarantees and low-level performance, but one of the concepts that initially leaves many developers scratching their heads is lifetimes. If you're here, you're likely grappling with lifetimes and perhaps wondering why Rust makes you explicitly annotate them in certain contexts. In this post, I'll help demystify lifetimes by breaking them down into simple, digestible concepts. We'll use a real-world analogy to make it stick, build up from an easy code example, and explore how lifetimes help Rust ensure memory safety. By the end of this article, you'll not only understand what lifetimes are, but why they exist and how to work with them confidently. Let’s dive in! Before we get into the details, let’…  ( 6 min )

"We replaced our workflows with Whispr. What we lost in productivity, we gained in existential clarity." I created a fake startup — Whispr — that offers “Silence-as-a-Service.” Neural Quietude Index™ and Void Engagement Coefficient. Zenith Voidwalker. Let’s be honest: most of us in tech don’t talk to each other, we communicate via tooling. So I asked: What happens if we remove all communication and pretend that’s an upgrade? “The OS of Nonverbal Presence.” Whispr is a fully silent productivity platform. The branding is pure Silicon Valley: Jargonized fake metrics ✅ Monospace font and sacred geometry ✅ A tagline that feels like it could be AI-generated or Buddhist ✅ 🔗 You can experience the void here People started asking for the SDK. One VC asked if it was invite-only. A designer offered to “collab on the brand strategy of the void.” The fun part? believable it became. Modern dev culture has over-optimized for: Articulating ideas Framing narratives Over-documenting “value” We don’t build products. performance rituals of doing work. Whispr isn’t satire — it’s just... slightly ahead. Whispr exposes how much of work is social positioning: Saying “let’s circle back” instead of “I don’t know” Writing strategy docs that no one reads Designing decks to impress other decks Silence removed all that. Good satire should feel plausible to those it mocks. Tech loves mysticism when it’s dressed in metrics. If you make your BS beautiful enough, someone will fund it. Whispr was never about silence. techno-rituals we mistake for clarity. In pretending to launch a joke, I accidentally diagnosed a condition. “Whispr changed nothing. That was the point.” — Me, probably mid-existential crisis, but silently.  ( 4 min )

Artificial intelligence is no longer a futuristic dream—it's quietly woven itself into every aspect of our lives. From healthcare diagnoses to music recommendations, from shopping habits to social connections, AI orchestrates our everyday experiences, shaping personal choices and broader societal outcomes. But there's a crucial caveat: are we becoming masters of this remarkable technology, or servants to its silent power? We're at a defining crossroads. The ethical compass we calibrate today determines the AI-driven world we wake up to tomorrow. Beyond the allure of machines and codes, technology carries a deeply human responsibility. It challenges us profoundly—asking us how we'll protect freedom, ensure fairness, and preserve dignity in an AI-infused world. Every digital step leaves foot…  ( 6 min )

Lots of features have been added since the last blog post. The addition of an interactive map is the biggest game-changer. The map is based on the Leaflet module, which is entirely open-source and free. It can pull imagery from any source, so I chose OpenStreetMap, since it is also free. In order to give visitors a true-to-scale overview of the farm's layout, I overlayed markers, zones, and paths on the map based on real coordinates. Most icons are stored on the server as SVGs, and then processed through a custom "icon factory" when they are needed. This makes it easy to add new icons, and reuse existing ones. The map has been made interactive by allowing certain elements to be clicked on, which will reveal a 'popup' with more content. Utilizing the JS navigator.geolocation API, I implemented a simple geolocation feature that refreshes every 8 seconds. Users can click the GPS button to center the map on their location. In order to reduce crowding and maintain the aesthetic appeal of the map, some icons and tooltips will disappear when zoomed out to certain levels. Additionally, zooming has been limited to level 16, and capped at level 19, since that is the maximum level OpenStreetMap will provide tiles for. This feature fully incorporates the map with the rest of the website. I've made a lightweight system that allows linking to specific coordinates via the URL query. This will enable visitors to be pointed directly to the location they're looking for without pouring over the map.  ( 3 min )

Frontend development has undergone significant changes in styling approaches. While methodologies like BEM and preprocessors like Sass previously dominated, today more and more teams are transitioning to the utility-first approach embodied in Tailwind CSS. This framework has fundamentally changed the perception of how CSS architecture should look in modern applications. Tailwind CSS is a utility-first CSS framework that provides a set of low-level utility classes for building custom user interfaces. Unlike component frameworks like Bootstrap or Bulma, Tailwind doesn't offer ready-made components but provides tools for creating them. The core philosophy of Tailwind is that instead of writing custom CSS, you combine small, reusable utility classes directly in your HTML markup. <!-- Tradition…  ( 5 min )

"Modern inter-process communication made simple. A refreshed IPC bus for local Node.js microservices." Hi everyone! Have you ever had to connect several Node.js processes running on the same machine? Maybe you're splitting a monolith into smaller pieces, running worker daemons, or coordinating local tools? Standard solutions like child_process, stdin/stdout, named pipes or TCP — they all work, but come with tons of boilerplate: serialization, routing, discovery, and error handling. This is where nodeBond comes in — a revived and redesigned lightweight IPC bus for local Node.js services. Yes, it’s an old idea — now completely reworked and updated in version 4.0.0 ✨ Setting up raw sockets is error-prone No built-in service discovery No shared in-memory state (without adding Redis or DB) Ha…  ( 4 min )

As artificial intelligence (AI) becomes an integral part of modern applications, developers are seeking programming languages that are not only powerful but also efficient and scalable. Kotlin—a modern, expressive, and pragmatic language—has emerged as a compelling choice for building AI-powered applications, particularly for Android and multiplatform development.

Hi, I'm Edith, this is my first post here and i just wanted to talk about something that has been bothering me, which is how AI usage is such a trap for beginner programmers. I'm giving my first hand experience. Apologies if its not all that i will get better at this with practice Okay, let me give you a scenario, you are a beginner programmer (like me) and you really wanna grasp concepts as soon as possible This was my toughest pill to swallow I wont lie haha... most of us who have passion for programming fail to acknowledge that its not as easy as we thought. You are learning a new language and this requires an identity shift which is the hardest thing to do especially if you are someone like me. You need to change how you think and approach problems. https://youtu.be/2-ePXrJZ5Oo?si=ouIXR1UZbwu1gRo_ As programmers the most important thing is learning from YOUR mistakes no matter how tedious. Understand your code and master the logic behind it and before anything make sure you think like a programmer; breakdown your problems and find logical solutions to them.

Introduction Today's post will be quite short, but I’m writing it down as a personal memo. I often use my DSLR for work, and after every shoot, I insert the SD card into my Mac to transfer the data. This error always appears when I press the eject button for the disk in Finder. Of course, I always ensure that the data transfer to the Mac is complete before attempting to eject, so there should be no procedural issues. Nevertheless, I never understood the cause and had been force ejecting the disk every time. But of course, this is not a good practice, and depending on the situation, it could potentially lead to disk damage, malfunction, or even data loss. Allowing such risky operations to become a habit is not ideal. lsof Command I decided to look into the issue a bit more today and f…  ( 5 min )

Intro The AI tooling landscape has exploded recently, and it can be overwhelming to sift through the noise. This review covers some tools I've found genuinely handy. There's also a really nice PDF report I've attached below, worth a read if you have the time. AI Tooling Review and Analysis Perplexity.ai excels at delivering concise answers with source citations, making it ideal for research and fact-checking. It blew my mind when I first started using it a few month back. It's magic yo. Google's Gemini offers a more integrated search experience, blending traditional search results with AI-powered summaries. Its deep integration with other Google services is a significant advantage (if you're ok with that...). I'd stick with the Pro model, as Flash tends to be good for simpler tasks. T…  ( 4 min )

Introduction If you've ever tried integrating Apple HealthKit into your fitness app, you've probably faced this frustrating step: "Which HKWorkoutActivityType should I use for this workout?"

Part 4: Manage Services Like a Sysadmin Ninja Part 5: Bonus Scripting Practice Final Words of Wisdom You’ve fired up your RHEL 9 VM, flexed your typing fingers, and bravely typed lsblk… only to be ghosted by /dev/sdb. But guess what? You’re still in the game. And this guide is for you — the Linux warrior who keeps going, one command at a time. If you tried lsblk and /dev/sdb is still in hiding, it's okay. You can still practice tons of RHCSA skills using the space and partitions you already have. Let’s pivot to the real-world RHCSA tactics you can conquer right now: Make your own top-secret coffee log: This is the command line equivalent of putting your diary under lock and key. Because every RHCSA candidate should know how to create a user who respects a properly brewed cup of the sweet bean juice. Create a loopback device — it's like a pretend disk: I'll admit, this was a hard one to grasp but perseverance and hard work paid off! I debated whether to keep my mistakes in and re-do it to make it look clear, but sometimes, we need to own our mistakes and embrace them, that's how we learn, and grow. Boom. Fake disk. Real experience. Zero stress. Learn to control services. Become the puppet master of your system. Create a basic shell script because scripts are sexy and RHCSA loves them: Save it as brew.sh, make it executable. Boom. You just automated a task. Hire yourself. Don’t let hardware hiccups stop your hustle. The RHCSA is as much about mindset as it is about commands. You’re learning. You’re practicing. And that’s more powerful than a second disk. Need help fixing VirtualBox or creating more real-world practice scenarios with what you have? I’ve got you. Just say the word.  ( 4 min )

Según nos están vendiendo continuamente, la IA (inteligencia artificial) ha conseguido un hito importantísimo, de tal manera que la IAG (inteligencia artificial general), está a la vuelta de la esquina... ¿es esto cierto? La investigación en IA comenzó en los años 40 del siglo XX. aunque el término IA no se acuñaría hasta 1956. El trabajo se centraría en la creación de máquinas inteligentes. Lo primero que se debatió fue... ¿qué es la inteligencia? ¿cómo puede definirse? Como no se llegó a ningún acuerdo o avance sobre este tema, Alan Turing crea su famoso Test de Turing. No se sabe qué es la inteligencia, pero si interactuando con un programa de computador este resulta ser indistinguible de un ser humano, entonces es inteligente.

Understanding the core internet protocols is essential for every developer. In this overview, we’ll explore the purpose, mechanics and typical use cases of IP, TCP, UDP and HTTP—all in a succinct, professional format. IP (Internet Protocol) IP provides logical addressing and packet routing across interconnected networks. Every device on the network is assigned an IP address (IPv4 or IPv6), which uniquely identifies its location. How It Works Packetization: Data is broken into discrete units called packets. Addressing: Each packet header contains source and destination IP addresses. Routing: Routers examine destination addresses and forward packets toward their target, potentially across multiple networks. Unreliable Delivery: IP makes no guarantees about packet delivery, order or duplicati…  ( 4 min )

AI models are becoming increasingly adept at processing data beyond just text. They can now take in images, audio, video, and even documents like PDFs. This ability to handle multiple types of input is known as multimodality, and it's starting to shape how developers build smarter, more flexible systems. In LangChain, multimodality is beginning to show up in different parts of the stack, from chat models that can describe images to embedding models that could one day support audio or video search. It’s still early, and the tooling isn’t fully standardized, but support is growing fast. So, here’s the exciting thing: We are currently working on Langcasts.com, a resource crafted specifically for AI engineers, whether you're just getting started or already deep in the game.

The Decline of Code Memory (and Why It Matters More Than You Think) How many times have you checked the React docs for the same useEffect example this month? Or maybe you just prompt your AI assistant and vibe your way through the code. Today, many developers rely less on memorizing syntax and more on tools that help complete or generate code quickly. That convenience comes at a cost: we’re gradually losing the ability to remember the code we write every day—and that matters more than you might think. Modern development has changed. We no longer need to memorize syntax, so we don’t. Instead, we search/prompt. We copy. We paste. Sometimes we don’t even understand the code we’re running—just that it works. This isn’t entirely bad; tools are meant to boost us. But there’s a hidden cost. We…  ( 4 min )

This week I had a couple of things I got stuck on and googling/Stack Overflow weren’t helping me much. I know that people have said that AI can help you with programming and I thought I’d see how much help it was getting me unstuck. I went a few rounds with it coming up with suggestion that sounded reasonable, but none of them helped. Although I found that telling it exactly what wasn’t working helped me to establish what the problem actually was. Sadly, though, it then started giving me code where I couldn’t see what it had changed. When I asked, it told me it had added a function. But that function was already there… At that point it become clear that it wasn’t going to be of any more help and I gave up.

“Choose boring technology.” — Dan McKinley (ex-Engineering at Etsy) In the age of constant innovation and shiny new frameworks, it’s tempting to jump on every new tool that promises to change your dev life. But sometimes, the best tool is the one you don’t notice—because it just works. Welcome to the case for boring tech. Boring tech isn't bad tech. It's well-established, stable, and widely understood. It’s PostgreSQL over some NoSQL flavor-of-the-month. It’s Rails or Django over the latest JS meta-framework. It’s SSH and cron instead of a complex CI/CD toolchain you don’t understand. Boring tech has survived years of production use. It has documentation, Stack Overflow threads, GitHub issues, and real-world success stories. Good luck finding a dev fluent in a 3-month-old build tool. With boring tech, there’s a bigger talent pool and faster onboarding. Shiny tools break. APIs change. Dependencies rot. Boring tech? It’s predictable—and predictability is a superpower in production. 🐘 PostgreSQL 🧱 jQuery (yes, still!) 📦 Docker 🐍 Python 🛠 Bash scripts 🔧 cron jobs 🧑‍💻 Git None of these make headlines—but they keep the digital world running. Of course, boring tech isn’t always the answer. Use cutting-edge tools when: Your problem is novel or evolving fast You're prototyping and optimizing later You want to experiment (and accept the risks) But in production? Simplicity scales. Tech isn’t about what’s coolest—it’s about what delivers reliably. If you want to ship, sleep, and scale, maybe it’s time to go back to basics. 🖋 Written by Juan G., builder of useful things and fan of predictable systems.  ( 3 min )

Understanding Linked Lists in Computer Science Linked lists are a fundamental data structure in computer science, forming the backbone of many complex systems and algorithms. Understanding them is crucial for any aspiring programmer or software engineer. This article will explore the different types of linked lists, their uses, historical significance, advantages, drawbacks, and why they remain incredibly relevant today. At its core, a linked list is a linear collection of data elements, called nodes. Unlike arrays, where elements are stored in contiguous memory locations, linked list nodes can be scattered anywhere in memory. Each node contains two key pieces of information: Data: The actual value stored in the node (e.g., a number, a string, or a more complex object). Pointer (or Link)…  ( 8 min )

When working with the Document Object Model (DOM) in JavaScript, one often encounters collections of elements rather than individual ones. One such collection type is the NodeList. Understanding what a NodeList is, how it differs from similar data structures like arrays, and how to work with it effectively is essential for writing robust and efficient JavaScript code. A NodeList is a collection of nodes returned by DOM methods such as document.querySelectorAll() or Node.childNodes. It represents a list of nodes in the order they appear in the document. const items = document.querySelectorAll('.item'); console.log(items); // NodeList of elements with class 'item' In this example, items is a NodeList containing all elements with the class item. There are two primary types of NodeList: Stati…  ( 4 min )

Want to level up your terminal output with cool animations, progress bars, and fancy ASCII art? This quick guide shows you how to combine three awesome Python libraries to do just that: pyfiglet — for eye-catching ASCII text banners. Why Care About Terminal Styling? When building CLI tools or scripts, output styling helps: Code Example import pyfiglet from tqdm import tqdm from rich.console import Console from rich.progress import track import time # ---------- 1. ASCII Art ---------- ascii_banner = pyfiglet.figlet_format("Nishkarsh!") print(ascii_banner) # ---------- 2. TQDM Progress Bar ---------- print("\n[1] Loading with tqdm:") for _ in tqdm(range(50), desc="Loading..."): time.sleep(0.02) # ---------- 3. Rich Progress Bar ---------- console = Console() print("\n[2] Fancy Progress with Rich:") for step in track(range(10), description="Processing tasks..."): time.sleep(0.1) # ---------- 4. Rich Spinner / Status ---------- print("\n[3] Animated Spinner with Rich:") with console.status("[bold green]Finalizing magic..."): time.sleep(2) console.print("\n[bold cyan]All done! Your terminal is now beautiful. 🌈[/bold cyan]") Output: What Happens Here? tqdm shows a simple progress bar with a label "Loading..." that fills up as the loop runs. rich’s track() gives a colorful, animated progress bar with the label "Processing tasks...". rich also lets you create a spinner with a status message (Finalizing magic...) to show a task in progress. Finally, it prints a colored success message with emoji to celebrate! How to Run This pip install pyfiglet tqdm rich Save the script as terminal_magic.py python terminal_magic.py What Else Can You Do? Combine rich’s tables, trees, and markdown for killer CLI apps.

I have been a programmer for many years, I admit I'm no where close to the best, but I kept plugging away and did accomplish some things that made people more productive, and maybe less frustrated. Along the way I learned that I needed to set limits on my boss, whoever they were at the time. Let me explain. One time the IT director told me I had gotten a bad review from a primary stakeholder. 'Never completed a project' I thought things were going along quite well, so how did that happen? This 'primary stakeholder' was always moving the end goal, or adding to the list of functions. Therefore, I was never finishing or reaching the end. From then on I needed a protection against bad reviews. No one had told me before that I needed a contract for work accomplished. I started writing up a project plan and had the stakeholder sign off, before work started, and when completed. Then they could add or change anything they liked. Only they first needed to acknowledge that this task was completed. That put an end to bad the reviews, and made everyone happier, especially me. :-)  ( 3 min )

Ever wanted to collect product feedback in real-time without managing a single server? This guide walks you through building a complete serverless feedback and rating system using AWS — powered by Lambda, DynamoDB, API Gateway, and CloudFormation! In the digital age, user feedback is gold. Whether you're building a SaaS product, running a blog, or launching a mobile app — understanding your users helps shape better experiences. But traditional feedback systems often involve: Managing EC2 instances Scaling backend services Writing complex logic for real-time updates This can be costly, time-consuming, and a real dev productivity killer. What if you could: Collect real-time feedback through a REST API? Instantly update ratings and analytics as new data arrives? Never manage a server again? T…  ( 4 min )

Welcome to the third part of our series on building AI agents with Strands! In Part 1: Creating Your First Agent, we created a simple agent that acts as a computer science expert, and in Part 2: Tool Integration, we enhanced it with custom tools, like a glossary of terms and the ability to directly access the web. Now, we'll integrate the Model Context Protocol (MCP) to connect our agent with external specialized services. You'll learn how to expand your agent's capabilities by connecting to any MCP server with just a few lines of code. Our use case: Connect your agent to a specialized quiz service - perhaps a platform provided by a university, or by a commercial vendor. For this tutorial, we'll build a simple quiz service to show the integration patterns, but in practice you'll often con…  ( 9 min )

JavaScript has long been the dominant language of the web. However, as applications have grown in complexity, developers have increasingly turned to TypeScript — a statically typed superset of JavaScript — to gain better tooling, improved readability, and fewer runtime errors. In this blog post, we’ll dive deep into TypeScript, exploring its features, benefits, and how to get started. What is TypeScript? Key Features of TypeScript Static Typing TypeScript introduces types to JavaScript. This means you can specify the type of a variable, function parameter, or return value, which helps catch type-related bugs early in the development process.

In the last article, I introduced the try-catch IIFE pattern. Some of you found it clever, while others couldn’t stand the syntax. And honestly? Fair. IIFE (Immediately Invoked Function Expression) can look odd at first glance. But I’m here to change your mind. IIFE isn’t just a relic of the var era, there are still many modern use cases. Here are 7 modern use cases of IIFE that go beyond legacy code and show how they can improve clarity, encapsulation, and expressiveness in your everyday code. var Era?) Before we look at modern use cases, let’s rewind a bit. IIFE stands for Immediately Invoked Function Expression. It's a function that runs right after it’s defined.

❗ Avoid .Wait() and .Result in Async Contexts – Here’s Why Calling .Wait() or .Result on a Task blocks the current thread until the Task completes. 🧠 Why? The result: Deadlock. public class DeadlockDemo { public static void Main() { Console.WriteLine("Starting..."); var result = GetData().Result; // ❌ This can deadlock in UI/ASP.NET Console.WriteLine($"Result: {result}"); } public static async Task GetData() { await Task.Delay(1000); // Simulate async work return "Hello from async!"; } } What happens? public class AsyncSafeDemo { public static async Task Main() { Console.WriteLine("Starting..."); var result = await GetData(); // ✅ Safe and non-blocking Console.WriteLine($"Result: {result}"); } public static async Task GetData() { await Task.Delay(1000); // Simulate async work return "Hello from async!"; } } Why this works: ❌ Avoid .Result or .Wait() in async contexts (can cause deadlocks). ✅ Use await to keep things async and non-blocking.  ( 3 min )

TLDR: We can test for equality, less-than and greater-than by using a combination of calc(), abs() and sign(). Others, such as Lea Verou, have written superb guides about using binary logic to perform conditions in CSS, using CSS Variables with values of 0 or 1. Until CSS supports @if and @else then we have to make do with such workarounds. Often however, we have numbers other than 0 or 1 in our CSS Variables so it would be handy if we could compare numeric values and drive logic from them. In JS we might simply write: if (a === b) { // Apply some styles } if (a > b) { // Apply some styles } but the best we could hope for in CSS right now is to set boolean variables like the following, and to use them in Binary Linear Interpolation: --isEqual: /* Some magical logic here */ --isGreaterThan: /* Some other magical logic */ Well there is a way, using calc() and the more recent abs() and sign(). Like this... --isNotEqual: sign(abs(calc(var(--a) - var(--b)))); --isEqual: calc(1 - var(--isNotEqual)); --isLessThan: sign(max(0, calc(var(--b) - var(--a)))); --isGreaterThan: sign(max(0, calc(var(--a) - var(--b)))); --isLessThanOrEqual: calc(1 - var(--isGreaterThan)); --isGreaterThanOrEqual: calc(1 - var(--isLessThan)); /* I'd welcome any suggestions for smarter ways to derive these! */ Demo on CodePen. Note: abs() and sign() have only partial browser support but they can be achieved using older syntax. At time of writing only Safari & Firefox supported them.  ( 3 min )

I remember the exact moment I realized I was doing it all wrong. It was 2 AM, and I was deep in my third "Learn React in 30 Days" tutorial. My browser had seventeen tabs open with different coding courses, my notepad was filled with “best practices” I'd copied from various blogs, and my GitHub? Completely empty. I felt productive. I felt like I was learning. But I wasn't getting anywhere. Then my friend, who started coding at the same time as I did—landed his first developer job.

Yesterday I told myself I would do something other than program all day, but again ended up pushing to accomplish the goal that I felt a bit obsessed over. The goal: to fine tune Mistral using my own method, in order to create a personalized lyric generation machine. I would be training it with my own lyrics as well as injecting random sequences of words. I just had to know the effect that fine-tuning would have. Would it really be able to make the kind of creative lyrics that I wanted? Base LLMs can't really generate the kind of poetry/lyrics that actual artists do in the real world. Usually they are very hard to wrangle toward being more creative. So I figured I would try an experimental fine-tuning method with Mistral to see what effect it could have.

In Next.js layout.tsx is a shared UI component between routes. layout.tsx never rerenders when we navigate from one route to another. We use layout to render static elements that are not supposed to be changed. Like, the Header, Footer, etc. It means, layout keeps your component/pages or UI the same way and renders the page.tsx in it as children, if you want. layout and template Just like layout template also wraps the pages and components as children. But the main difference between layout and template is, layout can keep the current state, but template can't. That's why layout does not change the UI or does not manipulate the DOM. On the other hand, template does not hold the state value. It changes the state rerenders the UI, and manipulates the DOM. Creating a template is very simple. Create a file named template.tsx/jsx/js.. in your desired directory. In the template, returning a React component is compulsory. Do as you do in layout.tsx import SignUp from './signup'; export default function MyTemplate({ children }: { children: React.ReactNode }) { return ( {children} ); } In summary, don't use template for static assets. Use it for where state needs to be changed and rerender the component. 'use client' Sometimes you may need to use 'use client'. When you use any React hook or state (useState, useEffect) in your template Attaches event handlers or relies on browser APIs (window, document) Imports other Client Components (e.g., a carousel, chart, or provider) Once "use client" is present, all imports become part of the client bundle.  ( 3 min )

“It’s not a bug, it’s an undocumented feature.” Every dev, at some point. Let’s face it. Debugging sucks especially when it’s 2 AM and the console is taunting you with cryptic errors. For years, I treated debugging like a necessary evil until I flipped the script. This post is about how I went from rage-quitting over bugs to actually enjoying the debugging process, and how you can do it too. Whether you're a junior dev, a bootcamp student, or a senior drowning in legacy code this is for you. A while ago, I spent 6 hours fixing a 6-line bug. Sound familiar? The turning point came during a code review. A senior dev casually said: “Don’t debug by guessing. Debug by isolating.” That sentence changed everything. Reproduce It Read the Error (Slowly) Add Minimal Logs Isolate and Comment Out Rubber Duck It 🧠 Tools That Took My Debugging to the Next Level React DevTools / Redux DevTools Network Tab in DevTools (Underrated!) Postman / Insomnia for API Isolation TypeScript + ESLint for early catches ✅ Bonus: My Debug Checklist (Save This) What was the last change before this started? Are all environment variables correct? Are third-party APIs/services up? Is this bug UI-related, logic-related, or data-related? Debugging isn’t just a skill. It’s a superpower that 10x’s your dev career. I now treat bugs as treasure maps each one leads to deeper understanding of the codebase. What’s your worst (or funniest) bug story? What’s one debugging trick you swear by? 👇 Drop it in the comments I’m reading every one.  ( 3 min )

In today’s fast-paced software development landscape, releasing code is only half the battle. Ensuring it runs reliably in production is where DevOps practices shine. A cornerstone of maintaining resilient systems is having a solid strategy for monitoring, logging, and observability. But what do these terms actually mean, and how do they fit together in a DevOps workflow? Let’s break it down and explore some tools and practices you can start using today. Understanding the Concepts Goal:-Detect and respond to system issues before users notice them. Tools to consider: Prometheus Logging: Goal:- Debug and trace problems with context-rich, searchable logs. Best practices: Tools to consider: Observability: Goal:- Empower teams to ask questions about system behavior and get answers—without deploying new code. Three pillars of observability: Metrics – Quantitative data (CPU, memory, latency). Tools to consider: OpenTelemetry (vendor-neutral standard) Putting It All Together workflow: -Instrument your code and infrastructure with OpenTelemetry or custom metrics. -Set up log collection and aggregation with tools like Fluentd and ELK. -Build dashboards and alerts in Prometheus + Grafana. -Enable tracing for microservices using Jaeger or Zipkin. -Continuously improve your alert thresholds and monitoring queries based on incidents and postmortems. N/B: You can monitor a system without truly understanding its inner workings. Observability closes that gap. Final Thoughts What tools and practices do you use for observability?

Markdown Markdown is a standardised way of writing documents to include formatting like headers, italics, bold, list, links, etc. Normally, there is not a mechanism within frameworks to directly translate markdown into rendered HTML. This guide may help you add this functionality to a Next.js project should you wish, like us, to add blogs to your site. Markdown itself is a lightweight markup language. You won't normally see the untranslated raw code, unless you are perhaps a Content Creator. You will normally see the rendered HTML result in a browser. An example of markdown might look like this: ## This is a header **This is bold** _And this is italic_ [I am a link](https://futools.online) - [ ] Task List Item 1 - [ ] Task List Item 2 - [ ] Task List Item 3 Which will render to this…  ( 6 min )

In the great geopolitical theatre of South Asia, Pakistan was often cast as the reactive actor — defending, surviving, recalibrating. But that script has been rewritten. Not through war, but through diplomacy, deterrence, and doctrine. India’s two-front war fantasy — engaging China in the north while destabilizing Pakistan in the west — was never a strategy rooted in reality. It was a media script designed to boost morale, push military spending, and sell the illusion of supremacy. That illusion fell apart in 2025. China’s decisive diplomatic entrance into Afghanistan, coupled with Pakistan’s security synchronization with the Taliban regime, ended India’s covert playground. RAW’s logistical networks, once thriving in Kandahar and Jalalabad, have dried up. And with the collapse of those cor…  ( 4 min )

Introducción: El Equilibrio Perdido en el Diseño de Bases de Datos En el mundo del diseño de bases de datos relacionales, existe una tendencia casi religiosa hacia la normalización perfecta. Los diseñadores novatos, armados con las reglas de Codd y la teoría relacional, se embarcan en cruzadas para eliminar cada vestigio de redundancia. Sin embargo, esta búsqueda obsesiva de la pureza teórica puede convertirse en una trampa que compromete gravemente el rendimiento, la mantenibilidad y la usabilidad práctica de los sistemas de bases de datos. Para entender por qué la sobre-normalización es problemática, primero debemos comprender qué representa cada forma normal desde una perspectiva algebraica.

You may have noticed that Google’s logo today is flat, colorful, and minimal — a big shift from the old serif-style version we saw in the early 2000s. But why the change? When Did Google Change Its Logo? Google last changed its logo on September 1, 2015. The previous version used a serif font with a more traditional look. The new logo features a sans-serif font, brighter colors, and a design optimized for digital platforms. Old Tech, Old Challenges Back then, CRT monitors didn’t show colors accurately, and early printers couldn’t match on-screen colors well. So, logos were kept simple, with basic colors and solid shapes to avoid issues in print and digital formats. Now Everything’s Digital Today, screens are high-resolution, color-accurate, and mobile-friendly. Printing tech has also caught up. Most importantly, our lives are now digital-first — so logos need to look great on screens of all sizes. Google’s 2015 logo update introduced a clean, modern, and scalable design. It’s easy to read, works across devices, and feels more playful and user-friendly — just like Google's services. What Do You Think? This is just my opinion based on how technology has evolved. But what about you?Do you think there’s another reason Google changed its logo?It feels like many brands are updating their logos these days — maybe Google just joined the trend too.  ( 3 min )

Throughout my life, I've tried to get on top of my finances and understand my financial performance. I experimented with numerous finance tracker apps, but none of them truly worked for me. The main issue was their demand for regular input—logging expenses, scanning receipts, categorizing transactions, and tracking goals. This felt like a burden, and I soon realized that I don't need to micromanage my transactions. It's pointless for me to know if this week's spending is higher than last week's, or if I spent more on clothes this month than usual. What I truly want is a high-level overview of my savings. Did my wealth increase over the year? Is it worthwhile to diversify savings between CNY and USD? What's the total of my savings spread across several banks, brokers, and crypto-wallets?

CSS sign() is not well supported but can be 'polyfilled' with calc & clamp: --input: 10; /* <-- Any number */ --num: calc(var(--input) * infinity); --sign: clamp(-1, var(--num), 1); Handy if you're attempting conditional logic and you need 0's and 1's instead of numbers. (What? Why? Read more about Binary Linear Interpolation). How it works: Multiply by infinity to give us 0 or +/- infinity to avoid rounding errors when dealing with very small decimals. Tip: If you know your input numbers will never be between -1 and 1 then you can skip the calc(). Round to the nearest -1, 0 or 1. Demo on CodePen:  ( 3 min )

It seems likely that common myths, like only techies need it, can leave individuals and businesses vulnerable.

Let me tell you a secret—I used to think CSS colors were boring. "Oh wow, hex codes, how thrilling," I’d say, rolling my eyes so hard I could see my own brain. But then I built this Ultimate CSS Colors Tool (Pro Edition™) and—plot twist—it turns out colors are actually kinda dope? Why This Tool is Different (And Why You’ll Actually Learn Stuff) Most color tutorials are like: "Here’s HEX, RGB, and HSL." "Good luck figuring out the rest, loser." Meanwhile, this tool is like: "Here’s HEX, RGB, HSL, HSLA, HWB, OKLab, OKLCH, Display-P3, and even CMYK (for some reason)." "Oh, you wanna play with sliders and see real-time changes? Say less." "Want to copy-paste code like a pro? Done." What You Get: ✅ All Color Formats Explained – From basic HEX to futuristic OKLCH. ✅ Interactive Playground – Because reading is hard, but clicking is fun. ✅ Real-World Use Cases – See how colors work in actual CSS (not just theory). ✅ Pre-Made Palettes – Tailwind, Material Design, Flat UI—steal them. I won’t tell. ✅ Copy-Paste Magic – One-click CSS snippets because we’re lazy geniuses. The Best Part? It’s Actually Useful You know those tutorials that teach you something and then you immediately forget it? Yeah, this ain’t that. Learn by doing (sliders! buttons! shiny things!) See contrast ratios (so you don’t blind your users) Export your colors (because memorizing hex codes is for psychopaths) Try It Yourself (Or Don’t, I’m Not Your Boss) If you’ve ever: Googled "CSS color formats" and got a 10-year-old blog post Struggled with HSL like it’s some kind of math test Wanted to use modern color spaces but had no idea how …then this tool is for you. 👉 [Check it out here] (or just stare at the pretty colors, I don’t judge). Final Thought: CSS colors don’t have to suck. This tool makes them almost fun. And if it doesn’t? Well, at least you got to play with sliders. Happy coloring! 🎨  ( 3 min )

Identifying Effective Figma Efficiency Boosters Evaluating Plugin Performance Okay, so you're trying to speed up your Figma workflow, right? Plugins are the way to go, but not all plugins are created equal. Some can actually slow you down if they're poorly coded or just too resource-intensive. The key is to test and monitor plugin performance regularly. Here's a simple way to think about it: Track loading times: How long does it take for the plugin to launch and complete its task? Monitor Figma's overall performance: Does Figma become laggy or unresponsive after installing the plugin? Check for conflicts: Does the plugin interfere with other plugins or Figma's core functionality? It's also worth checking out user reviews and ratings.

When deciding between Java and Kotlin for backend development, understanding their key strengths is essential. Java has long been the industry standard for building robust, scalable backend systems with a vast ecosystem and mature frameworks like Spring Boot. It offers excellent performance, strong community support, and extensive libraries, making it a reliable choice for enterprise applications. On the other hand, Kotlin is rapidly gaining popularity for backend development due to its concise syntax, null safety features, and seamless interoperability with Java. Kotlin’s modern language design reduces boilerplate code, which speeds up development and improves code maintainability. It also supports coroutines, enabling efficient asynchronous programming that’s perfect for building high-performance backend services. Both languages integrate well with popular tools and cloud platforms, but Kotlin is often preferred in new projects looking for modern solutions, while Java remains dominant in legacy systems and large-scale applications. Ultimately, your choice should consider factors like project requirements, team expertise, and future scalability. Staying updated with current trends, frameworks, and cloud-native development can help you make the best decision for backend programming in 2024.  ( 3 min )

Lately, I’ve been seeing stories that genuinely shock me - managers deliberately sabotaging production, creating chaos, or manipulating deadlines just to see how their devs react under pressure. Let’s be clear: this isn’t leadership. This is abuse. You don’t build trust or resilience by throwing your team into trauma scenarios. You don’t foster collaboration by making people suffer. And you definitely don’t promote “team skills” by manufacturing stress. That’s not psychological safety - that’s psychological warfare. If this happened in any other field - construction, demolition, food service - the manager would be gone. Immediately. Because putting people at risk for the sake of your curiosity or ego is unacceptable. Just because developers work at desks doesn’t mean they aren’t affected. Burnout is real. Mental exhaustion is real. People leave not because they’re weak - but because they’re being used as stress test dummies. You don’t test loyalty by creating chaos. You earn it by creating clarity. You don’t build team skills through sabotage. You build them through support. We need to stop celebrating toxic “leadership” and start holding it accountable.

Graph databases have long been synonymous with social media platforms—Facebook, LinkedIn, Twitter. But what if I told you they’re powering much more than just your friend lists and follower graphs? In this post, I’ll show you why graph databases are becoming mission-critical for industries like cybersecurity, fraud detection, recommendation engines, and even SEO—and how you can start using them today. Traditional relational databases are amazing—for structured, tabular data. But as soon as relationships become complex and interconnected, they fall short. Enter graph databases. These are designed to treat relationships as first-class citizens. Nodes (entities) and edges (connections) make modeling real-world scenarios effortless. Here’s where they shine outside of social networks: Fraud D…  ( 4 min )

If you’ve ever run a Sprint Retrospective and felt like the energy in the (virtual) room was flat — or your team just wasn’t that responsive — I’ve been there. In the early days of my Scrum Master journey, I struggled with exactly that. But over time, I picked up a few tricks that helped me turn retrospectives into something more valuable, more honest, and a lot more fun. One of those tricks? Adding a dose of nostalgia and creativity. Today, I’ll walk you through a fresh retro board I created — my Warner Bros Retro Board, built in Mural — and show how it helped my team open up, reflect better, and even laugh a little during retros.

In recent years, MongoDB and PostgreSQL have gained popularity, representing the NoSQL and SQL camps, respectively. Each technology is optimized for different data modeling approaches: PostgreSQL serves as a general-purpose relational database, while MongoDB functions as a general-purpose document database. While one is more data-centric and the other more application-centric, both can handle similar workloads. PostgreSQL offers flexibility over relational with its JSONB datatype, and MongoDB's flexible schema allows for some normalization through references and schema validation. However, designing a document database as a relational one is inefficient, and vice versa. Although PostgreSQL can superficially resemble a document database with JSON datatypes, it is not optimized for using it …  ( 3 min )

Operational issues don’t usually appear overnight – they tend to build up slowly, gradually affecting how efficiently processes run. Many companies, no matter their size or industry, experience similar challenges. Let’s take a look at some of the most common ones below. Manual processes Many businesses rely on manual tasks, especially during their early growth stages. But as data and customer numbers increase, routine work takes up more time. This can lead to employee overload and slower response times. Instead of progressing, companies often end up spending more time correcting mistakes. Lack of real-time analytics When data is scattered across multiple spreadsheets, files, or systems, it becomes challenging to get a clear and accurate view. This often means decisions are based on intuiti…  ( 4 min )

I had the benefit of joining the AWS Community Day in Zürich this week, most went as expected but, then an interesting question came up....Does caching in API Gateway create vulnerabilities for products using Authorizer Caching? When your users call your API, you have an obvious need to verify these requests should actually be allowed. I've talked extensively about this in my academy article on what the @#!? is Auth. Even if you haven't read that article, if you are well versed in the need for users to authenticate and authorize to your specific service API and endpoints, then you get the gist. So you have a need to verify the access tokens sent by users on ever request. When using AWS this means using API Gateway, and when using API Gateway that likely means you'll be using an API Gateway…  ( 6 min )

When a customer checks out on an e-commerce site and clicks “Pay,” a complex series of processes kicks off in milliseconds. This post breaks down what happens behind the scenes of a payment gateway, how it integrates into digital storefronts, and what makes the entire process secure and compliant. A payment gateway acts as a bridge between the merchant’s website and the broader financial ecosystem — including issuing banks, acquiring banks, and payment networks. Its primary role is to: Capture and encrypt payment information Authenticate and authorize transactions Communicate results back to the e-commerce platform All of this occurs in real time, typically in under 2–3 seconds. 1. Checkout Begins 2. Tokenization 3. Authorization Request 4. Authentication (Optional / 3DS / OTP) 5. Response 6. Callback or Webhook For a broader look at the payment methods modern e-commerce platforms support — from cards to UPI and wallets — you can check out this deep dive on how different e-commerce payment systems work. Security is critical throughout. Here's how it's enforced: PCI DSS Compliance: Merchants using hosted solutions are often considered SAQ-A level — the lowest risk level — since card data is never stored or handled directly. SSL Encryption: All communication between browser, merchant server, and gateway is encrypted. Tokenization: Replaces sensitive data with tokens, reducing data breach risks. 3D Secure / OTP: Adds an extra layer of authentication for card transactions. HMAC-Signed Webhooks: Used to verify that callbacks are genuinely from the gateway. Plug-and-Play vs Custom Integrations Though often invisible to users, payment gateways form a vital layer in e-commerce architecture. Their ability to securely connect the merchant, customer, and financial institutions — in a matter of seconds — is what makes modern online commerce possible.  ( 4 min )

Communication with preverbal infants is a fundamental aspect of caregiving that sets the foundation for language development and emotional connection. While infants begin to understand language from birth, their ability to express themselves verbally develops gradually over time. Baby sign language offers a proactive approach to enhancing communication during this critical stage by introducing simple gestures that infants can use to convey their needs and emotions. This innovative strategy not only facilitates earlier communication but also reduces frustration for infants who may struggle to articulate their desires through speech alone. The concept of baby sign language is rooted in the belief that infants possess the cognitive ability to understand and replicate gestures before mastering…  ( 5 min )

Looking to secure your web app, but overwhelmed by complex firewall rules and confusing configurations? You’re not alone. In 2025, developers—especially beginners—need a Web Application Firewall (WAF) that’s powerful and practical. That’s where SafeLine WAF comes in. Most traditional WAFs rely on regular expressions (regex) to detect attacks. A common engine like ModSecurity powers over 80% of WAFs globally. Let’s take a look at how they work: union[\w\s]?select — matches when both “union” and “select” appear \balert\s*\( — matches common XSS patterns like alert( Sounds logical, right?

MongoDB, as a mainstream NoSQL database, has become a powerful tool for handling unstructured data thanks to its flexible document structure. However, as anyone who’s used it knows, its computing capabilities leave much to be desired. The trade-off of NoSQL is sacrificing the simplicity of SQL. Let’s take the example of finding the top 10 customers by order amount. With SQL, you can accomplish the task with a single SELECT TOP 10 statement. However, with MongoDB, you’ll need to use these three operators: $group, $sort, and $limit, and implementing cross-collection joins requires painstakingly chaining multiple $lookup stages – akin to manually assembling building blocks step by step. What’s even more frustrating is that advanced operations like window functions simply can’t be implemented …  ( 4 min )

Imagine spending hours daily cleaning phone numbers and sending 1,000 WhatsApp messages by hand. That was my reality last year, juggling lead follow-ups for 20+ clinics. Then I had an idea: what if I could automate it all in one place? This is the story of Konquista — how I went from manual chaos to a full-fledged SaaS using Google Sheets, Flask, and Django, boosting response rates by 30%. Here’s how it happened. We had just onboarded SocialHub to manage communication across 20+ clinics using multiple WhatsApp numbers via their API. Leads were flowing in — but the process to follow up with those who didn’t schedule was messy: Extract leads from the partner platform Clean phone numbers (+55, 11, (11), -, etc.) Match leads with internal ERP data Use VLOOKUP in Excel to compare both sides S…  ( 4 min )

In November, I registered my Bluesky account and was immediately impressed by its rapidly growing and vibrant community. With the platform’s user base soaring to 27 million, Bluesky has focused on stabilizing its services, leaving some key features (like bookmarks) yet to be implemented. At the same time, I noticed an exciting trend: developers were actively creating tools to enhance the Bluesky experience, while users were on the hunt for the best solutions. However, there wasn’t a centralized hub for discovering or promoting these tools, and this inspired me to create bskyinfo—a comprehensive directory for the Bluesky community. Here’s how I turned the idea into reality in just one week: Identifying the Opportunity Bluesky’s rapidly expanding community created both a need and an o…  ( 4 min )

📘 Scenario Setup You have the following Git commit history and some uncommitted changes: A commit - "A code" B commit - "B code" C commit - "C code" D commit - "D code" --> Working directory has "E code" (uncommitted changes) git reset --soft What it does: Moves the HEAD pointer back to commit B Keeps your current working directory as is C and D are removed from commit history but remain in your code All changes (C, D, E) are staged (ready to be recommitted) ✅ Good for: Squashing commits or redoing commit history 🗂️ Result: E code, D code, C code = still in files and staged Git only shows A -> B in the commit log git reset --hard What it does: Moves the HEAD pointer back to commit B Deletes all changes made after commit B from both the history and your code Everything from C, D, and E will be wiped from disk ⚠️ Warning: This is destructive and not recoverable unless you use git reflog 🗂️ Result: Only A code and B code remain All changes after B are lost 🧠 Summary Table Reset Type Do code C/D/E remain in files? Do commits after B stay in history? git reset --soft ✅ Yes ❌ No git reset (default = --mixed) ✅ Yes (unstaged) ❌ No git reset --hard ❌ No (code deleted) ❌ No Use git log to find the commit hash you want to reset to Use git reflog if you need to recover accidentally lost commits after a --hard reset 📌 Stay safe — commit often and back up before using --hard!

While containers offer a convenient and efficient way to package applications, they still share the host’s kernel, which introduces a set of security concerns. Every process inside a container has the potential to make system calls to the host kernel, and that opens the door to possible exploitation. Docker’s support for seccomp (short for secure computing mode) provides a vital mechanism for limiting the system calls that containers are allowed to make. This significantly reduces the potential for abuse if a container is ever compromised. Seccomp works by allowing or denying specific system calls made by processes. Linux exposes hundreds of system calls, but the vast majority of containerized applications only need a small subset to function. By filtering out unnecessary or dangerous syst…  ( 5 min )

In software development, words alone often fail us. “simple dashboard,” the PM imagines a KPI-heavy screen, and the developer delivers a login page. Not due to incompetence—just a lack of shared visual understanding. Imagine this: you're a tree trying to describe a bird. amphibious fish. ✅ Technically functional. This is why visual designs aren’t nice-to-have—they’re essential. You don’t need high-fidelity UI every time. Visual design includes: ✏️ Wireframes (rough structure) 🧩 Mockups (detailed visuals) 🧻 Whiteboard sketches (quick flows) 📄 Paper doodles (yes, even that) Even a crude sketch on paper can align teams better than a 10-minute explanation. Here’s what visual clarity unlocks: 🧭 Aligned intent – Everyone’s on the same page ⏱️ Faster delivery – Build once, not three times 🔍 Caught edge cases early – Before they’re in production 📢 Inclusive feedback – Even non-tech folks get it A visual is a contract of understanding. Before your next sprint, pick up a pen or open a whiteboard—even if the result looks like abstract art. Your future self (and your dev team) will thank you.  ( 3 min )

If you're building modern, internet-facing applications on AWS, here’s a simple but powerful update you’ll love: EC2 Public DNS names now support IPv6 (AAAA records). 🎉 Before: EC2 Public DNS names (like ec2-203-0-113-25.compute-1.amazonaws.com) only pointed to the IPv4 address (A record) of your EC2 instance. If your instance was IPv6-only, the DNS name didn’t work. You had to: Use the raw IPv6 address (ugly and hard to manage), or Set up a custom domain using Route 53. Now: EC2 Public DNS names also return AAAA records that point to your instance’s IPv6 address. This means: You can access your EC2 instance over IPv6 using the default AWS DNS name — no extra setup needed. You launch an EC2 instance with only an IPv6 address: IPv6: 2600:1f18:abcd::1234 DNS: ec2-203-0-113-25.compute-1.amazonaws.com Before: You had to use: http://[2600:1f18:abcd::1234] Now: You can just use: http://ec2-203-0-113-25.compute-1.amazonaws.com And it’ll resolve to your IPv6 address automatically! 🎯 This update: Makes IPv6 adoption easier Removes the need for custom DNS hacks Supports a smoother transition to dual-stack or IPv6-only environments Helps future-proof your cloud apps It's a small change, but it removes friction from a common use case — especially for teams prioritizing IPv6, building scalable APIs, or serving international customers. 💬 Have you started moving to IPv6?

Sideloading apps on iOS has always been a cat-and-mouse game. Unlike Android, where APKs can be freely installed, iOS enforces strict rules: all apps must be signed and typically installed via the App Store. But in 2025, there are still several ways—some official, some unofficial—to install unsigned or non-App Store apps on an iPhone. Let’s explore the main sideloading methods that work today, how they technically function, and the pros and cons of each. 🔹 AltStore (Apple ID Certificate Signing) AltStore uses Apple’s official development certificate infrastructure to let users self-sign apps using a free Apple ID. When you log in to AltStore, it sends a request to Apple’s developer portal to generate a temporary provisioning profile tied to your Apple ID, device UDID, and app bundle ID. E…  ( 4 min )

As someone who's used SafeLine WAF for over a year, I was thrilled to get early access to their latest update — version 7.2.3 — and no, this isn’t a sponsored post. I reached out myself to try it, and here's my honest take. One of the highlights in this version is the Waiting Room, a new feature built to defend against HTTP flood attacks by smoothing traffic spikes — essentially a smarter rate limiter. The concept is simple but powerful: "When too many users access the site at once, the Waiting Room kicks in to flatten the traffic peak." Sounds like a queue system? That’s exactly what it is. And it works beautifully. Unlike traditional DDoS attacks that flood bandwidth, HTTP flood attacks target the application layer (Layer 7).

Full Title: Serverless vs Client-Side Rendering vs Dynamic Content (Server-Side Rendering) vs Compiled/Code Generation for Static Sites There is a lot of confusion about the term "dynamic website" for laypeople. Let's clear that up first: "dynamic" here doesn't mean sleek animation or any sort of table filtering—it refers to whether the website content itself is variable, can change based on conditions, or is fetched from some server or database. The essence of a dynamic website is that it's constructed at runtime, can change based on conditions, and is opposed to "static," meaning the contents are fixed and will not change unless someone modifies the source. In the case of the web, the source usually means the HTML itself. Also, "serverless" doesn't mean there is no server. There must be …  ( 5 min )

To Diagnose Overdraw, we can use developer options android and turn on the debug GPU overdraw. Tutorial on turning on developer options and Debug GPU overdraw: Enable Developer options. Click on the Build Number multiple times. Fig 1. Enable Developer Options** Enable Debug GPU Overdraw. Fig 2.

🚀 The Upgrade That Changes Everything When React 19 dropped, I hesitated. Another major version? More breaking changes? But after testing it, I realized—this isn’t just an update, it’s a revolution. From auto-optimizing performance to built-in hooks we’ve begged for, React 19 makes development faster, cleaner, and more powerful. Here’s what you need to know, the best supporting libraries, and how to upgrade without headaches. 👉 Full deep dive on Medium 🔥 React 19’s Game-Changing Features 1. The New React Compiler (Bye, useMemo!) No more manual memoization—React auto-optimizes re-renders now. Before: const memoizedList = useMemo(() => heavyCalculation(data), [data]); After: Just write normal code. React handles the rest. 2. Actions API (Simpler Data Handling) …  ( 4 min )

INTRODUÇÃO Object Calisthenics me fizeram lembrar de vários conceitos de Orientação a Objetos e eu gostaria de aplicar os mesmos raciocínios em typescrip. Não apenas portar o código para outra sintaxe, mas conseguir traduzir as necessidades e a estratégia para outro modelo de tipagem. O terceiro exercício de calistenia é bem frutífero para análise da linguagem porque expõe restrições e recursos que divergem em fundamento da abordagem clássica. Uma definição possível, por William Durand: 3. Wrap All Primitives And Strings Following this rule is pretty easy, you simply have to encapsulate all the primitives within objects, in order to avoid the Primitive Obsession anti-pattern. If the variable of your primitive type has a behavior, you MUST encapsulate it. Após o uso desta técnica continu…  ( 6 min )

To evaluate the concordance of VL quantification, we conducted a Bland-Altman analysis. Anticipated to reach over 50% prevalence, by 2030, individuals with bipolar disorder (BD) will be predominantly aged 50 or above. Yet, older age bipolar disorder (OABD) has not been studied thoroughly enough. Although large-scale prospectively collected data organized by key dimensions is constrained, it potentially allows for investigating several fundamental questions regarding BD's effect on this patient subgroup. The co-occurrence of latent tuberculosis and hepatitis B virus (HBV-LTBI) in the U.S. population lacks thorough epidemiological study. This study aims to evaluate the approaches to LTBI testing and the rate of LTBI in two substantial U.S. cohorts of adults with chronic hepatitis B (CHB). …  ( 7 min )

Ever build a business app that runs perfectly, only for users to… hate it? Been there. You’ve got clean endpoints, automated workflows, bulletproof logic—and yet support tickets keep coming in like: “Can’t find the thing I need.” “Where’s the Save button?” “This page is weird on my phone.” Turns out, bad UX can ruin even the best backend. “It Works Fine” Isn’t the Same as “It’s Usable” As devs, we’re often laser-focused on functionality. That makes sense. We want our apps to be fast, secure, and integrated properly. But if nobody can use what you built without training, duct tape, or daily rants, that’s not a win. That’s a failure in disguise. Here are 5 UX sins I’ve made (and seen) way too many times—plus how I avoid them now using Bellini, our app builder at Lonti. 1. Trying to Fit E…  ( 4 min )

Coming back to typed 100% AWS Lambda API’s, I’m convinced the config module is an anti-pattern if you’re using TypeScript. Been away from typed server-side for about 4 years. While the 1st I had ReScript on the back-end in Amplify, the rest of the companies I was at did JavaScript/Python. In those languages, dynamic, sleek, easy to use global variables are nice for smaller projects with quick deploys. Like types? Nope; all the allure dynamic languages have for “use a global proces.env.NODE_ENV to grab some dev.json that is magically inherited from default.json” suddenly screams “Why is this all un-typed, un-parsed without Zod, not wrapped in a Result, and why is config not used via dependency injection? Globals… in 2025?” Then you realize… you don’t even need anything beyond some simple types + 1 helper function, and you’ve got a type safe, environment aware configuration. First define your default config, equivalent to config’s “default.json”. Second, define your dev and prod config, extending the default (both in types and in values). Finally, create a get method, passing in process so you can unit test it with a stub vs. using it as a global variable. An improvement would be to pre-parse NODE_ENV so you don’t need a default in the switch. JavaScript, I’m fine with the config module. In TypeScript, it’s dangerous and shouldn’t be used in Node.js.  ( 3 min )

Have you ever build something for months… only to realize no one actually wants to use it? That was us. We had what we thought was a solid mobile app. The idea was validated. The features were there. But when we finally launched, the numbers just didn’t add up: High drop-off during onboarding Users signing up, but never coming back Confused feedback like “I don’t get what I’m supposed to do” At first, we thought it was a marketing issue. But turns out—it was our UX. The Pain Wasn’t the Product. It Was the Experience. If you’ve ever seen a user just stare blankly at your app screen and then close it, you know the pain. So We Got Help—From People Who Actually Do This for a Living Clear user journeys Tiny details like button placement and loading feedback Making sure users feel in control—not overwhelmed That’s when we came across a UX team in Singapore called Codigo. We weren’t even looking for an agency at first. But their UX case studies caught our eye—especially how they think through micro-interactions and user psychology. It wasn’t just design—it was experience strategy. Why I’m Recommending Them (Even Though I Don’t Usually Do This) We worked with Codigo because we needed real UX help, and they delivered. What I appreciated most: They interviewed our users before designing anything Their clickable prototypes were ready within weeks Every feedback loop felt like a collaboration, not a handoff Long story short: our bounce rate dropped, engagement rose, and people finally “got” the app. What You Can Learn (Even If You Don’t Hire Anyone) Don’t assume users think like you Fancy UI means nothing without flow clarity Test your onboarding with someone’s mom or uncle. Seriously. Final Thought They’ve worked with banks, startups, and even government apps. But most importantly, they get that UX isn’t a luxury—it’s the core of your product. 👉 If you’re curious, here’s their UX approach: https://www.codigo.co/services/user-experience No fluff. Just good, human-centered design.  ( 4 min )

Hello everyone. I have taken the CS5O's introduction to programming with python offered by Havard university, which I consider a wonderful experience on my programming journey. The issue is, I have built my final project which requires a graphical user interface, so I used python's tkinter library and ttkbootstrap. But to my greatest surprise, when I copy-paste my final result, which I tested many times in my local editor (pyCharm), into their online editor for submission, I noticed that their online editor doesn't support windows creation (tkinter and ttkbootstrap). My concern is, can I still move on to submit it? Will they consider it a valid final project or I need to change project. Your pieces of advice are welcome!  ( 3 min )

By: Alireza Minagar, MD, MBA, MS As a neurologist, software engineer, and AI ethicist, I’ve come to realize that some of the deepest insights in our field don’t come from new tools or libraries — but from enduring principles that have been with us for millennia. In this article, I pose a timeless question: What can we, as modern technologists, learn from the ancient builders of the Egyptian pyramids? You might be surprised how deeply the architectural mindset of ancient Egypt — forged in the sands of time — still resonates in today’s world of: System design Human coordination Ethical foresight These themes echo not only through ancient stone, but also through the codebases, AI models, and cloud infrastructure we build today.

PSA: Do not enable BitLocker unless you immediately activate it with your windows account. Friends don't let friends have BitLocker enabled unless they activate it. So, someone comes to me with a laptop - water damage, doesn't power on, ect. It's my job to simply take out the hard drive and grab whatever data I can. Ok, no problem right? It's all fun and games until I remove the hard drive from the computer and try to access it. BitLocker. WHY. Why do you have BitLocker enabled if you didn't activate it with your windows account? Here is the hard truth: If you have BitLocker enabled without activating it and something happens - like water damage - all the IT support in the world isn't going to be able to get your data. When the hard drive is removed from the original device, BitLocker is triggered. But you will never know your key to get access to your own information unless you had previously activated your key. Your assorted data, important business information, and family photos are NOT SAFE. They will be lost. Options: Save to the cloud Do routine backups elsewhere Disable BitLocker Fully activate BitLocker Do not live in limbo, you are playing with fire, only to the disadvantage of yourself! I spent the entire day, trying to figure out how I could get the data for a loyal customer. You know how bad that sucks when you can't even do the thing you are supposed to be able to do... I tried anyways. I spent all day googling work-arounds and trying a few things. Massive waste of time. Even if they can log into their Microsoft account, they will not have their BitLocker key if it was not activated. Go forth now, and save everyone.  ( 3 min )

Understanding Cross-Platform Design Principles The Importance of Consistency Across Platforms Consistency is super important when you're designing for different platforms. Think about it: users expect a certain level of familiarity no matter where they are interacting with your product. Maintaining a consistent look and feel builds trust and makes your product easier to use. Here's why it matters: Brand Recognition: Consistent visuals reinforce your brand identity. User Familiarity: Reduces the learning curve for users switching between platforms. Improved Usability: Predictable interactions lead to a better user experience. User Experience Considerations in Cross-Platform Design User experience (UX) is not a one-size-fits-all deal. What works great on a desktop might be a total disaster …  ( 6 min )

Understanding the 5-Layer Architecture of Modern Applications In software development, a well-structured application architecture is essential for building scalable, maintainable, and testable systems. One of the most widely used architectural patterns is the 5-layer architecture, which separates the application into logical layers, each with a specific responsibility. Let’s dive into each layer and understand its role in the system. The Presentation Layer is the topmost layer that users interact with directly. It displays data to the user and sends user commands to the application.

The current structure of capital markets is failing to serve a broad base of investors, according to Akshay BD, non-chief marketing officer at the Solana Foundation. During a panel at the Accelerate 2025 conference, Akshay argued that blockchain technology could help address these shortcomings, claiming that Solana could “make everyone an investor or a dreamer over time.” Akshay noted growing uncertainty among investors, citing concerns from investment managers who report heightened anxiety among clients. “You have low bond yields, you have asset price bubbles, and people don't really know how the traditional asset allocation model works anymore,” he said. The 60-40 portfolio hasn’t delivered consistent returns in a long time.” He attributed some of this tension to a widening gap between i…

Blockchain privacy tools such as zero-knowledge (ZK) proofs will become increasingly necessary to protect online user data in the age of artificial intelligence, according to Eran Barak, CEO of Shielded Technologies, the developer behind the Midnight privacy chain. In an interview with Cointelegraph at Consensus 2025, Barak said corporate service providers and centralized servers are expected to become honeypots for AI-assisted hackers and malicious actors looking to steal valuable data, including private keys, financial metadata, medical records, and government documents. Hackers targeting centralized entities have a "massive" return on investment (ROI) and are incentivized to hack centralized targets that contain millions of valuable records, the CEO told Cointelegraph. Barak added that …

Semler Scientific, a medical device company, purchased of $50 million worth of Bitcoin between May 13 and May 22, bringing the market value of the company’s Bitcoin (BTC) holdings to $474.4 million, keeping it within the top 13 of BTC Treasury companies. According to a May 23 disclosure, Semler bought a total of 455 BTC for an average purchase price of $109,801. To buy the Bitcoin, Semler Scientific used proceeds from an at-the-market stock offering program. So far, the company has sold roughly 3 million shares of common stock for net proceeds of $115 million. Semler Scientific’s shares have fallen 1.36% on the same day as the disclosure, though the decrease in its share price is largely in line with the Nasdaq’s performance. That index, which follows top tech stocks, is down 1% on the day. Semler Scientific share price.

Despite the claimed success of its Bitcoin treasury plan, Semler Scientific’s shares have dropped 18% in 2025, according to Google Finance. Bitcoin treasury companies, or companies that traditionally sell equity or issue debt to buy BTC, had been drawing the interest of investors looking for exposure to Bitcoin price fluctuations.

Texas Governor Greg Abbott has signaled support for a bill recently passed by the state House of Representatives that would establish a strategic cryptocurrency reserve. In a May 22 X post, Abbott posted a Techstory article about Texas state lawmakers’ efforts to create a Bitcoin (BTC) reserve. The story pointed out that the decision for the passage of SB 21, the bill in question, now rests on Abbott’s shoulders, roughly three months after it was introduced.  Since taking office, Abbott referred to himself as a “crypto law proposal supporter” in 2021 and suggested that he would support policies to establish Texas as a “crypto capital” in 2024. Texas was one of a handful of state-level governments that proposed setting up a strategic crypto reserve after the 2024 federal elections.    Rela…

When Venezuela was experiencing hyperinflation, Ledn co-founder Mauricio di Bartolomeo hedged against the collapsing local currency by shorting it in favor of the more stable US dollar. Today, he’s using a similar strategy — this time borrowing against his Bitcoin (BTC) to hedge against the crumbling US dollar. Di Bartolomeo connected with me during Canada Crypto Week in Toronto, where he talked about the advantages of Bitcoin-backed loans and the rapid growth of collateralized BTC lending. In our interview, he made a compelling case for continuing to stack sats, even as Bitcoin’s price keeps rising. This week’s Crypto Biz dives into our conversation with the Ledn co-founder and covers the latest business news from the blockchain world. A lesson from hyperinflation Before Bitcoin, di Barto…

Members of the US House of Representatives called for the Justice Department to investigate Donald Trump’s May 22 dinner for his top memecoin investors, citing concerns about “foreign influence over US policy decisions” and “potential corruption and emoluments clause violations.” In a May 22 letter to the Justice Department, 35 House members asked the public integrity section acting chief, Edward Sullivan, to launch an inquiry over the memecoin dinner to determine whether it violated the federal bribery statute or the foreign emoluments clause of the US Constitution.  Under the emoluments clause, a US president is barred from accepting any gift from a foreign state without the approval of Congress. Bloomberg reported that a majority of the attendees at the memecoin dinner were likely forei…

Key takeaways: Short-term Bitcoin holders realized $11.6 billion in profit over the past 30 days, suggesting a potential pause or local top in the market. Technical indicators show cooling momentum as retail investor sentiment falls to a 90-day low and liquidity data points to price volatility. Bitcoin (BTC) price recently hit a new all-time high of $111,800, but the bullish momentum may slow down as onchain data from Glassnode reveals significant profit-taking by short-term holders (STHs), potentially signaling a market "breather." Glassnode analysis shows that STHs, often considered traders rather than long-term investors, have realized a staggering $11.6 billion in profits over the last 30 days. This follows a sharp rebound in Bitcoin’s price, pushing past the STH cost-basis of $93,0…

Key points: Bitcoin slipped below $109,588, but technical charts suggest traders are buying each dip. Excessive leverage in Bitcoin futures increases the risk of a quick correction.

Sellers have pulled Bitcoin (BTC) back below the breakout level of $109,588, but lower levels are likely to attract buyers. Investor interest remains strong, with the US spot Bitcoin exchange-traded funds witnessing inflows of $934 million on May 22 and $608 million on May 21, according to SoSoValue data. Glassnode noted that the all-time high above $109,588 led to a total profit-taking volume of roughly $1 billion, far more muted than the $2 billion when the price rose abov…

Opinion by: Grigore Roșu, founder and chief executive officer of Pi Squared For some, the audacity of questioning the primacy of blockchain in Web3 is borderline heretical. The idea that decentralization and progress could exist without blockchains seems absurd to those who built careers around Bitcoin, Ethereum, and their descendants. Given blockchain's well-documented scaling limits, however, there is an argument to be made that Web3 doesn't actually need blockchains to thrive. Instead, it requires payment systems and verifiable settlement systems that are super fast. Blockchains are just one way to achieve that, not the only way. While blockchain solved the double-spending problem, it introduced its own architectural burden: the rigid fixation on total ordering, dictating that every tra…

The top 220 holders of US President Donald Trump’s memecoin met yesterday at the president’s golf course in Virginia for an exclusive dinner and purported meet-and-greet. Attendees spent a grand total of $148 million for an “ultra-exclusive VIP reception with the president,” which crypto industry advocates and critics alike saw as a potential opportunity to discuss crypto policy with the president.  The crowd contained a number of foreign crypto executives and influencers who otherwise would not have access to the US president, raising questions around corruption and foreign influence.  Concerns were further augmented when White House Press Secretary Karoline Leavitt declined to release a list of attendees, stating that the event was a private affair outside of Trump’s presidential duties.…

Understanding the Curve Finance DNS hijacking On May 12, 2025, at 20:55 UTC, hackers hijacked the “.fi” domain name system (DNS) of Curve Finance after managing to access the registrar. They began sending its users to a malicious website, attempting to drain their wallets. This was the second attack on Curve Finance’s infrastructure in a week. Users were directed to a website that was a non-functional decoy, designed only to trick users into providing wallet signatures. The hack hadn’t breached the protocol’s smart contracts and was limited to the DNS layer. The DNS is a critical component of the internet that functions like a phonebook. It allows you to use simple, memorable domain names (such as facebook.com) instead of complex numerical IP addre…

The bounty offer to recover stolen funds from Sui-based decentralized exchange (DEX) Cetus closely resembles a successful strategy used by a Solana project three years ago. It turns out that Cetus shares the same development team as Crema Finance, a Solana-based DeFi project that suffered a $9-million hack in 2022 but recovered most of the funds by negotiating with its hacker. Now, Cetus is relying on the same strategy. Cetus is asking the hacker to return all but $6 million, or 2,324 Ether (ETH), of the stolen funds in exchange for a promise not to pursue legal action. The protocol lost $223 million to an exploit on May 22. The size of the bounty has sparked backlash from users, with many calling for a formal compensation plan instead. Several community members argue that even if funds ar…

Decentralized finance (DeFi) platforms have a major cost advantage over traditional banks when it comes to onboarding new users, according to Anton Bukov, co-founder of decentralized exchange (DEX) 1inch. Speaking at a panel during Dutch Blockchain Week on May 22 in Amsterdam, Bukov said traditional banks spend between $100 and $300 per user to verify documents and set up accounts. Online banks, he said, spend about $20 to $30. In contrast, DeFi requires almost nothing beyond a smartphone and internet access. “Onboarding to DeFi literally costs zero,” Bukov said. “You don’t need brick-and-mortar infrastructure or lengthy verification processes. Just connect and transact.”  Bukov said that this gives DeFi an edge over traditional financial institutions in reaching the 1.4 billion unbanked p…

Is Tether MiCA compliant? The EU’s new Markets in Crypto-Assets regulation, better known as MiCA, is the first major attempt by a global economic power to create clear, region-wide rules for the crypto space, and stablecoins are a big focus. MiCA mandates best practices. If a stablecoin is going to be traded in the EU, its issuer has to follow some stringent rules: 1. You need a license To issue a stablecoin in Europe, you must become a fully authorized electronic money institution (EMI). That’s the same kind of license traditional fintechs need to offer e-wallets or prepaid cards. It’s not cheap and it’s not quick.  2. Most of your reserves have to sit in European banks This is one of the most controversial parts of MiCA. If you issue a “significa…

Automation is often depicted as a simple story of people versus machines—a narrative filled with apprehension and fear. Indeed, the anxiety surrounding job displacement is firmly rooted in historical experiences where technological leaps have abruptly reshaped employment landscapes. Yet this picture of conflict and competition misses a profound truth: automation isn’t merely replacing work—it’s fundamentally reshaping our relationship with work. Rather than being adversaries, humans and artificial intelligence (AI) are becoming partners in an evolving dance of productivity, creativity, and innovation. To grasp automation’s complex role, consider that old jobs have always faded with time—and with change comes rebirth. Current research, including findings from the World Economic Forum, consi…  ( 5 min )

Let’s get this out of the way up front: If you’re calling yourself a leader but treating your junior devs like interns with Stack Overflow accounts — you’re not leading. You’re just delegating down and hoping for the best. Junior devs aren’t liabilities. They’re high-potential humans still figuring out how this industry works while we dump half-documented codebases and broken CI pipelines on them like it’s a rite of passage. Time to do better. Here’s how real tech leaders actually support their junior devs: Don’t just toss a JIRA ticket and bounce. Give them the why, not just the what. “This feature helps us reduce user churn by tightening onboarding” is miles better than “Add this button to the modal because the PM said so.” Juniors thrive when they understand the system they’re working…  ( 4 min )

Machine learning (ML) algorithms analyze data to uncover patterns and generate insights. Based on their training approach and objectives, they can be categorized into four main types: Supervised learning uses labeled data (input features + corresponding output labels) to train models. The algorithm learns to map inputs to outputs, making predictions on new, unseen data. It’s divided into three key tasks: Classification: Predicts discrete categories (e.g., spam detection). Regression: Predicts continuous values (e.g., house prices). Forecasting: Predicts future trends (e.g., weather forecasts). Example: Predicting stock prices or customer churn. Unsupervised learning works with unlabeled data, identifying hidden structures or patterns. Since there’s no "correct answer" provided during training, the algorithm explores similarities/differences autonomously. Common techniques include: Clustering: Groups similar data points (e.g., customer segmentation). Dimensionality Reduction: Simplifies data while preserving key features (e.g., PCA for visualization). Example: Market basket analysis or anomaly detection. A hybrid approach combining small amounts of labeled data with large unlabeled datasets. This is cost-effective when labeling data is expensive or time-consuming. Applications: Speech recognition, medical image analysis. RL trains an agent to make decisions via trial and error, using feedback from rewards/penalties. The agent learns optimal strategies by interacting with an environment. Use Cases: Game AI (e.g., AlphaGo), robotics, autonomous vehicles.  ( 3 min )

You’ve added startSession() and startTransaction() to your Mongoose code, only to be greeted with: Transaction numbers are only allowed on a replica set member or mongos If you’re running MongoDB in a standalone Docker container, transactions simply won’t fire — because MongoDB requires a replica set (even if it’s just one node) to support transactions. Let’s break this down from the ground up — no prior MongoDB knowledge assumed. A replica set is a group of MongoDB processes that maintain the same data set. One member is the primary, which receives all write operations. The others are secondaries that replicate (copy) data from the primary in real time. Primary: accepts reads (depending on your read preference) and all writes. Secondary: copies data from primary; can optionally serve re…  ( 6 min )

When you're building a change data capture (CDC) pipeline with PostgreSQL, one of the first decisions you'll make is which output plugin to use. These plugins determine how your database changes get formatted and delivered—whether you're replicating to another Postgres instance, streaming to Kafka, or delivering changes to a webhook. But what exactly are these plugins, and how do they differ in practice? Let's dive in with a concrete example and explore your options. To understand how different output plugins work, let's start with a simple scenario. We'll set up logical replication, make a change, and see how different plugins format that change. First, you need to enable logical replication in PostgreSQL. You can read the Sequin docs to get specific instructions for Postgres providers li…  ( 7 min )
